Crystal structure of the two-dimensional coordination polymer poly[di-μ-bromido-bis(μ-tetrahydrothiophene)dicopper(I)]

ABSTRACT: Treatment of CuBr with tetrahydrothiophene produces a layered coordination polymer. The polymeric title compound, [Cu2Br2(C4H8S)2]n, CP1, represents an example of a two-dimensional coordination polymer resulting from reaction of CuBr with tetrahydrothiophene (THT) in MeCN solution. The two-dimensional layers consist of two different types of rhomboid-shaped dinuclear Cu(μ2-Br)2Cu secondary building units (SBUs); one with a quite loose Cu⋯Cu separation of 3.3348 (10) Å and a second one with a much closer intermetallic contact of 2.9044 (9) Å. These SBUs are interconnected through bridging THT ligands, in which the S atom acts as a four-electron donor bridging each Cu(μ2-Br)2Cu unit in a μ2-bonding mode. In the crystal, the layers are linked by very weak C—H⋯·Br hydrogen bonds with H⋯Br distances of 2.95 Å, thus giving rise to a three-dimensional supramolecular network.

Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]].

Project description:Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra are rotated and tilted due to N-H⋯Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetra-chloridoplumbate (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].

Project description:The title compound, [CuBr(C(9)H(9)N(5))](n), prepared by the solvothermal treatment of CuBr with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, is a new homometallic Cu(I)-olefin coordination polymer in which dinuclear Cu(2)Br(2) units are linked by the organic olefin ligand 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, which acts as a bidentate ligand connecting two neighbouring Cu(2)Br(2) units through the pyridine N atom and the double bond of the allyl group. The coordination of Cu(I) is slightly distorted tetrahedral.

catena-Poly[N,N,N',N'-tetra-methyl-ethylendi-ammonium [[tetra-bromido-antimonate(III)]-μ-bromido] hemihydrate].

Project description:The asymmetric unit of the title compound {(C6H18N2)2[Sb2Br10]·H2O} n , consists of two tetra-methyl-ethylendi-ammonium cations that are located on centres of inversion, as well as one tetra-methyl-ethylendi-ammonium cation, one water mol-ecule, one distorted octahedral [SbBr6](3-)anion and one bisphenoidal [SbBr4](-) anion in general positions. The [SbBr6](3-) and [SbBr4](-) anions are linked together by two long Sb-Br bonds of 3.2709 (8) and 3.5447 (7) Å into {[Sb2Br10](4-)} n chains along [001]. One of the three tetra-methyl-ethylendi-ammonium cations is disordered and was refined using a split model (occupancy ratio 0.58:0.42). The cations and the water mol-ecule are connected to the {[Sb2Br10](4-)} n polymeric anions by weak N-H ⋯Br and O(water)-H ⋯Br hydrogen bonding.

catena-Poly[[?-bromido-(?-hydroxydi-2-pyridylmethano-lato-?N,O:O,N')dicopper(II)(Cu-Cu)]-di-?-bromido].

Project description:The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801?(5)?Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H?O hydrogen bonds are present in the crystal structure.

Poly[tetra-aqua-?(4)-bromido-di-?(2)-bromido-?(2)-hydroxido-di-?(3)-iso-nicotinato-tetra-?(2)-isonicotinato-tetra-copper(I)dithulium(III)].

Project description:A new thulium(III)-copper(I) heterometallic coordination polymer, [Cu(4)Tm(2)Br(3)(C(6)H(4)NO(2))(6)(OH)(H(2)O)(4)](n), has been prepared by a hydro-thermal method. The Tm and both Cu atoms lie on mirror planes. The Tm atom is seven-coordinate with a capped distorted trigonal-prismatic coordination geometry, while the Cu atoms adopt trigonal CuBrN(2) and tetra-hedral CuBr(3)N coordination modes, respectively. The Cu atom in the trigonal coordination environment is disordered over two sites of equal occupancy. The crystal structure is constructed from two distinct units of dimeric [Tm(2)(?(2)-OH(IN)(6)(H(2)O)(4)] cores (IN = isonicotinate) and one-dimensional inorganic [Cu(4)Br(3)](n) chains, which are linked together, forming heterometallic Cu-halide-lanthanide-organic layers.

Crystal structure of di-μ-tri-hydro-(penta-fluoro-phenyl)-borato-tetra-kis-(tetra-hydro-furan)-disodium.

Project description:The title compound, [Na(μ-C6F5BH3)(C4H8O)2]2, represents a dimeric structure of sodium and organoborohydride, located about a centre of inversion. The Na⋯B distances of 2.7845 (19) and 2.7494 (18) Å were apparently longer than the Li⋯B distances (2.403-2.537 Å) of the lithium organotri-hydro-borates in the previous reports. Moreover, an inter-action between the sodium atom and one fluorine atom on the 2-position of the benzene ring is observed [Na-F = 2.6373 (12) Å]. In the crystal, the dimeric mol-ecules are stacked along the b-axis via a π-π inter-action between the benzene rings.

The one-dimensional coordination polymer poly[tetra-kis-[(4-chloro-phen-yl)methanaminium] [cadmate-μ-cyclo-hexa-phospho-rato]].

Project description:Cyclo-hexa-phospho-ric acid (P(6)O(18)H(6)) reacts with cadmium carbonate and 4-chloro-benzyl-amine (CBA) to give the mononuclear title complex, (C(7)H(9)ClN)(4)[Cd(P(6)O(18))](n), in which the Cd(II) atom, lying on an inversion centre, has an octa-hedral coordination built of six O atoms of two centrosymmetric P(6)O(18) rings. Each P(6)O(18) ligand acts as a bridge, linking two Cd(II) atoms and forming an anionic coordination polymer [Cd(P(6)O(18))(4-)](n) extending along [010]. Adjacent polymeric chains are connected through N-H⋯O and C-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular network.

Crystal structure of the unusual coordination polymer catena-poly[[gold(I)-μ-1,2-bis-(di-phenyl-phosphino-thio-yl)ethane-κ2 S:S'] di-bromido-aurate(I)].

Project description:In the title compound, {[Au(C26H24P2S2)][AuBr2]} n , the gold(I) centres of the cation are coordinated by the P=S groups of the di-sulfide ligands to form a chain polymer parallel to the c axis. Both independent gold atoms lie on the same twofold axis, and the midpoint of the H2C-CH2 bond lies on an inversion centre. The anions flank the polymeric chain; they are connected to it by short aurophilic inter-actions and C-H⋯Br contacts, and to each other by Br⋯Br contacts.

Hydro-thermal synthesis and crystal structure of poly[bis-(?3-3,4-di-amino-benzoato)manganese], a layered coordination polymer.

Project description:The hydro-thermal synthesis and crystal structure of the title two-dimensional coordination polymer, poly[bis-(?3-3,4-di-amino-benzoato-?3 N 3,O,O')manganese(II)], [Mn(C7H7N2O2)2] n , are described. The Mn2+ cation (site symmetry ) adopts a tetra-gonally elongated trans-MnN2O4 octa-hedral coordination geometry and the ?3-N,O,O' ligand (bonding from both carboxyl-ate O atoms and the meta-N atom) links the metal ions into infinite (10) layers. The packing is consolidated by intra-layer N-H?O and inter-layer N-H?N hydrogen bonds. The structure of the title compound is compared with other complexes containing the C7H7N2O2 - anion and those of the related M(C8H8NO2)2 (M = Mn, Co, Ni, Zn) family, where C8H8NO2 - is the 3-amino-4-methyl-benzoate anion.
