One-dimensional ladder gallium coordination polymer.

ABSTRACT: A one-dimensional ladder-type coordination polymer, poly[[(?2-hydroxido)(?2-1H-pyrazole-3,5-di-carboxyl-ato)gallium(III)] monohydrate], [Ga(C5H2N2O4)(OH)(H2O)] n or [Ga(HPDC)(OH)(H2O)] n , I, isotypic with a V3+ coordination polymer previously reported by Chen et al. [J. Coord. Chem. (2008). 61, 3556-3567] was prepared from Ga3+ and pyrazole-3,5-di-carb-oxy-lic acid monohydrate (H3PDC·H2O). Compound I was isolated using three distinct experimental methods: hydro-thermal (HT), microwave-assisted (MWAS) and one-pot (OP) and the crystallite size should be fine-tuned according to the method employed. The coordination polymeric structure is based on a dimeric Ga3+ moiety comprising two ?2-bridging hydroxide groups, which are inter-connected by HPDC2- anionic organic linkers. The close packing of individual polymers is strongly directed by the supra-molecular inter-actions, namely several O-H?O and N-H?O hydrogen-bonding inter-actions.

One Dimensional Coordination Polymer of Zn(II) for Developing Multifunctional Nanoparticles.

Project description:A variety of nanoparticles (NPs) including Ag, Au, Pd, Cr and mixed Cu/Fe have been synthesized in a non-activated (without solvent removal) one dimensional coordination polymer (CP) of Zn(II) via two different mechanisms, acid formation and redox activity of the framework. Main driving force to grow these NPs within the cavities of CP is the presence of free oxygens of one of the monodentate carboxylate groups of BDC ligand. These free oxygens act as anchoring sites for the metal ions of the metal precursors. Chemical and physical characteristics of the NPs within the framework have been evaluated by the high resolution transmission electron microscopic (HRTEM) images. Excluding Ag(0) and Pd(0) other NPs are present as combinations of their elemental as well as oxide forms (Au/Au2O3, Cr/Cr2O3/CrO2 and Cu/Cu2O, Fe/FeO). Synthesized Ag NPs within the framework show remarkable antibacterial efficacy at extremely low concentrations. Ag, Au and Cu/Fe NPs show ferromagnetic properties within the framework at room temperature. This polymer has potential to sequester highly toxic Cr(VI) to non toxic Cr(0), Cr(III) and Cr(IV) species.

A one-dimensional coordination polymer constructed from isatine-3-oximate and sodium.

Project description:The reaction of hydroxyl-amine hydro-chloride with isatin in ethanol, catalysed with HCl and neutralized with Na(2)CO(3), yielded the one-dimensional coordination polymer, catena-poly[[[aqua-sodium]-di-?-aqua-[aqua-sodium]-bis-(?-2-oxoindoline-2,3-dione 3-oximato)] tetra-kis-(oxoindoline-2,3-dione 3-oxime)], {[Na(C(8)H(5)N(2)O(2))(H(2)O)(2)]·2C(8)H(6)N(2)O(2)}(n). The Na(I) atom has a six-coordinate distorted-octa-hedral environment. Isatine-3-oximate O atoms and water mol-ecules bridge adjacent Na atoms, forming a one-dimensional polymeric structure parallel to [100]. Each isatine-3-oxime dimerizes through N-H?O interactions and in addition each oxime is linked to a coordination polymer. Thus, coordination polymers are linked by O-H?O and O-H?N interactions from isatine-3-oxime dimers, building a two-dimensional network parallel to [110].

Sodium 2-nitro-cinnamate dihydrate: a one-dimensional hydrogen-bonded coordination polymer.

Project description:The title compound catena-poly[aqua-sodium-μ(2)-aqua-μ(3)-2-nitro-cinnamato], [Na(C(9)H(6)NO(4))(H(2)O)(2)](n), the sodium salt of trans-2-nitro-cinnamic acid, is a one-dimensional coordination polymer based on six-coordinate octa-hedral NaO(6) centres, comprising three facially related monodentate carboxyl-ate O-atom donors from separate ligands (all bridging) [Na-O = 2.4370 (13)-2.5046 (13) Å], and three water mol-ecules (two bridging and one monodentate) [Na-O = 2.3782 (13)-2.4404 (17) Å]. The structure is also stabilized by intra-chain water-carboxyl-ate and water-nitro O-H⋯O hydrogen bonds.

A new one-dimensional NiII coordination polymer with a two-dimensional supra-molecular architecture.

Project description:A new one-dimensional NiII coordination polymer of 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene, namely catena-poly[[aqua-(sulfato-κO)hemi(μ-ethane-1,2-diol-κ2O:O')[μ3-1,3,5-tris-(1H-imidazol-1-ylmeth-yl)benzene-κ3N3,N3',N3'']nickel(II)] ethane-1,2-diol monosolvate monohydrate], {[Ni(SO4)(C18H18N6)(C2H6O2)0.5(H2O)]·C2H6O2·H2O} n , was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The NiII cation is coordinated by three N atoms of three different 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene ligands, one O atom of an ethane-1,2-diol mol-ecule, by a sulfate anion and a water mol-ecule, forming a distorted octa-hedral NiN3O3 coordination geometry. The tripodal 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene ligands link the NiII cations, generating metal-organic chains running along the [100] direction. Adjacent chains are further connected by O-H⋯O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (001) plane. Another water mol-ecule and a second ethane-1,2-diol mol-ecule are non-coordinating and are linked to the coordinating sulfate ions via O-H⋯O hydrogen bonds.

Copper(II) 2,2-Bis(Hydroxymethyl)Propionate Coordination Compounds with Hexamethylenetetramine: From Mononuclear Complex to One-Dimensional Coordination Polymer.

Project description:Three new copper coordination compounds derived from 2,2-bis(hydroxymethyl)propionic acid (dmpa) and hexamethylenetetramine (hmta) were obtained and their crystal structures were determined. The stoichiometry of the reagents applied in the syntheses reflects the metal to ligand molar ratio in the formed solid products. Due to the multiple coordination modes of the used ligands, wide structural diversity was achieved among synthesized compounds, i.e., mononuclear [Cu(dmp)2(hmta)2(H2O)] (1), dinuclear [Cu2(dmp)4(hmta)2] (2), and 1D coordination polymer [Cu2(dmp)4(hmta)]n (3). Their supramolecular structures are governed by O-H•••O and O-H•••N hydrogen bonds. The compounds were characterized in terms of absorption (UV-Vis and IR) and thermal properties. The relationships between structural features and properties were discussed in detail. Owing to discrepancies in the coordination mode of a dmp ligand, bidentate chelating in 1, and bidentate bridging in 2 and 3, there is a noticeable change in the position of the bands corresponding to the stretching vibrations of the carboxylate group in the IR spectra. The differences in the structures of the compounds are also reflected in the nature and position of the UV-Vis absorption maxima, which are located at lower wavelengths for 1.

A one-dimensional ladder-like coordination polymer: poly[[hexa-aqua-bis(μ-5-nitro-benzene-1,3-dicarboxyl-ato-κO,O',O'')(μ-oxalato-κO,O':O'',O''')diyttrium(III)] trihydrate].

Project description:In the crystal structure of the title one-dimensional coordination polymer, [Y(2)(C(8)H(3)NO(6))(2)(C(2)O(4))(H(2)O)(6)]·3H(2)O, each Y(III) ion is bridged to its neighbours by two 5-nitro-benzene-1,3-dicarboxyl-ate (nbdc) dianions and one oxalate dianion (located on an inversion centre) to form a ladder-like polymeric structure. The two carboxylate groups of nbdc assume different modes of coordination, one is chelating whereas the other is monodentate. Three water mol-ecules coordinate to the Y(III) ion to complete an eight-coordinate distorted dodecahedral geometry. The ladder-like polymers are assembled together by hydrogen bonding and π-π stacking [centrio-centriod distance = 3.819 (9) Å] in the crystal structure.

One-Dimensional ?-d Conjugated Coordination Polymer for Electrochromic Energy Storage Device with Exceptionally High Performance.

Project description:The rational design of previously unidentified materials that could realize excellent electrochemical-controlled optical and charge storage properties simultaneously, are especially desirable and useful for fabricating smart multifunctional devices. Here, a facile synthesis of a 1D ?-d conjugated coordination polymer (Ni-BTA) is reported, consisting of metal (Ni)-containing nodes and organic linkers (1,2,4,5-benzenetetramine), which could be easily grown on various substrates via a scalable chemical bath deposition method. The resulting Ni-BTA film exhibits superior performances for both electrochromic and energy storage functions, such as large optical modulation (61.3%), high coloration efficiency (223.6 cm2 C-1), and high gravimetric capacity (168.1 mAh g-1). In particular, the Ni-BTA film can maintain its electrochemical recharge-ability and electrochromic properties even after 10 000 electrochemical cycles demonstrating excellent durability. Moreover, a smart energy storage indicator is demonstrated in which the energy storage states can be visually recognized in real time. The excellent electrochromic and charge storage performances of Ni-BTA films present a great promise for Ni-BTA nanowires to be used as practical electrode materials in various applications such as electrochromic devices, energy storage cells, and multifunctional smart windows.

Crystal structure of a one-dimensional coordination polymer of tin(IV) bromide with 1,4-di-thiane.

Project description:The title compound, [SnBr4(C4H8S2)] {systematic name: catena-poly[[tetrabromidotin(IV)]-?-1,4-dithiane-?(2) S:S']}, represents the first 1,4-di-thiane complex with tin as coordination centre. The asymmetric unit consist of half a formula unit with the tin(IV) atom at the centre of symmetry at 0,0,1/2 (Wyckoff symbol b) and a centrosymmetric 1,4-di-thiane mol-ecule with the centre of symmetry in 1/2,0,1 (Wyckoff symbol c). The tin(IV) atom is coordinated in a distorted octa-hedral manner by the four bromine atoms and two sulfur atoms of two 1,4-di-thiane mol-ecules in a trans-position. Sn-Br [mean value: 2.561?(5)?Å] and Sn-S distances [2.6546?(6)?Å] are in the typical range for octa-hedrally coordinated tin(IV) atoms and the di-thiane mol-ecule adopts a chair conformation. The one-dimensional polymeric chains propagate along the [101] direction with weak inter-molecular Br?Br [3.5724?(4)?Å] between parallel chains and weak Br?H inter-actions [2.944-2.993?Å] within the chains.

Explosive and pollutant nitroaromatic sensing through a Cd(II) based ladder shaped 1D coordination polymer.

Project description:In the existing leanings of environmental and national security issues, establishment of appropriate sensors for explosive as well as pollutant nitroaromatic compounds may be considered as one of the most prodigious job for material researchers. In the current study a new Cd(II) based 1D ladder coordination polymer (CP), [Cd(4-bpd)(3-cbn)2]n, has been synthesized and well characterized through single crystal X-ray diffraction analysis. Interestingly, the supramolecular assembly of this compound has efficiently identified 2,4,6-trinitrophenol through fluorescence quenching method. The Stern-Volmer coefficient (Ksv) has been calculated as 6.047 × 103 M-1, which can be attributed to the quenching of the emission intensity. The limit of detection (LOD) has been determined as 0.260 μM following the 3σ method along with almost 95% fluorescence intensity reduction. FESEM study revealed that the crystalline nature of the compound has been altered upon interaction with the above mentioned nitroaromatic analyte. Theoretical studies were performed to get the insight idea of fluorescence quenching mechanism which also substantiated the experimental observation. The present study can pave the way for the fabrication of future generation technology in sensor field.

A one-dimensional HgII coordination polymer based on bis-(pyridin-3-ylmeth-yl)sulfane.

Project description:The reaction of mercury(II) chloride with bis-(pyridin-3-ylmeth-yl)sulfane (L, C12H12N2S) in methanol afforded the title crystalline coordination polymer catena-poly[[di-chlorido-mercury(II)]-μ-bis-(pyridin-3-ylmeth-yl)sulfane-κ2N:N'], [HgCl2L] n . The asymmetric unit consists of one HgII cation, one L ligand and two chloride anions. Each HgII ion is coordinated by two pyridine N atoms from separate L ligands and two chloride anions. The metal adopts a highly distorted tetra-hedral geometry, with bond angles about the central atom in the range 97.69 (12)-153.86 (7)°. Each L ligand bridges two HgII ions, forming an infinite -(Hg-L) n - zigzag chain along the b axis, with an Hg⋯Hg separation of 10.3997 (8) Å. In the crystal, adjacent chains are connected by inter-molecular C-H⋯Cl hydrogen bonds, together with Hg-Cl⋯π inter-actions [chloride-to-centroid distance = 3.902 (3) Å], that form between a chloride anion and the one of the pyridine rings of L, generating a two-dimensional layer extending parallel to (101). These layers are further linked by inter-molecular C-H⋯π hydrogen bonds, forming a three-dimensional supra-molecular network.
