Studies on Magnetic and Dielectric Properties of Antiferromagnetically Coupled Dinuclear Cu(II) in a One-Dimensional Cu(II) Coordination Polymer.

ABSTRACT: A one-dimensional Cu(II) coordination polymer with encapsulated antiferromagnetically coupled binuclear Cu(II) has been synthesized by using 5-nitroisophthalic acid (5-N-IPA) and 4-aminopyridine (4-APY) [Cu2(5-N-IPA)2(4-APY)4] n (1). Electrical properties are examined by complex impedance (Z*), dielectric permittivity (?*), and ac conductivity studies at different frequencies (10 kHz-5 MHz) and temperatures (253-333 K). The contribution of grain and grain boundary has been explained by a different theoretical model. The variable temperature magnetic susceptibility data for compound 1 were recorded between 300 and 2 K. The shape of the curve (?M T vs T) indicates dominant antiferromagnetic coupling, which results from the interaction between the copper(II) atoms.

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.

One-dimensional ladder gallium coordination polymer.

Project description:A one-dimensional ladder-type coordination polymer, poly[[(μ2-hydroxido)(μ2-1H-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 μ2-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.

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.

Enhanced dielectricity coupled to spin-crossover in a one-dimensional polymer iron(ii) incorporating tetrathiafulvalene.

Project description:In designing multifunctional materials for potential switches that can be used as memory devices, the high-spin (HS) to low-spin (LS) crossover (SCO) one-dimensional polymer, [FeII(L)(4,4'-bpy)] n , was constructed from a designed redox-active tetrathiafulvalene (TTF) functionalized Schiff-base and the ditopic linker 4,4'-bipyridine (bpy). It exhibits an 8 K hysteretic SCO centred at T 1/2 = 325 K which is coupled to changes in its dielectric constant. The crystal structures above and below the transition temperature reveal similar parallel linear ···Fe-bpy-Fe-bpy··· chains displaying expansion of the FeII octahedron in the HS state. Density functional theory (DFT) calculations reveal a concerted electronic charge and spin change represented by the Mülliken charge of the Fe and the magnitude and direction of the dipole moment which substantiate the experimental observations.

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.

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.

Poly[di-μ-glycinato-copper(II)]: a two-dimensional coordination polymer.

Project description:The title coordination polymer, [Cu(C(2)H(4)NO(2))(2)](n), is two-dimensional and consists of a distorted octa-hedral copper coordination polyhedron with two bidentate glycine ligands chelating the metal through the O and N atoms in a trans-square-planar configuration. The two axial coordination sites are occupied by carbonyl O atoms of neighbouring glycine mol-ecules. The Cu-O distances for the axial O atoms [2.648 (2) and 2.837 (2) Å] are considerably longer than both the Cu-O [1.9475 (17) and 1.9483 (18) Å] and Cu-N [1.988 (2) and 1.948 (2) Å] distances in the equatorial plane, which indicates a strong Jahn-Teller effect. In the crystal, the two-dimensional networks are arranged parallel to (001) and are linked via N-H⋯O hydrogen bonds, forming a three-dimensional arrangement.
