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

ABSTRACT: The polymeric title compound, [Cu₂Br₂(C₄H₈S)₂] _n , CP1, represents an example of a two-dimensional coordination polymer resulting from reaction of CuBr with tetra-hydro-thio-phene (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 inter-metallic contact of 2.9044 (9) Å. These SBUs are inter-connected 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 supra-molecular network.

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.

Poly[tetra-aqua-μ(4)-bromido-di-μ(2)-bromido-μ(2)-hydroxido-di-μ(3)-iso-nicotinato-tetra-μ(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)(μ(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.

Poly[[μ(2)-1,2-bis-(4-pyrid-yl)ethene-κN:N']-di-μ(3)-bromido-dicopper(I)].

Project description:In the title polymeric Cu(I) compound, [Cu(2)Br(2)(C(12)H(10)N(2))](n), the Cu cation is coordinated by an N atom from the 1,2-bis-(4-pyrid-yl)ethene ligand and three Br(-) anions in a distorted tetra-hedral CuBr(3)N coordination geometry. Each Br(-) anion bridges three Cu cations related by inversion centers, forming a stair-like polymeric chain along the a axis, and the terminal N atoms of the 1,2-bis-(4-pyrid-yl)ethene ligand, located across an inversion center, coordinate the Cu cations from neighboring chains, forming polymeric sheets.

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)].

Di-μ-bromido-tris-(triphenyl-phosphine)-1κP,2κP-disilver(I) tetra-hydro-furan 0.85-solvate.

Project description:In the title binuclear silver(I) complex, [Ag(2)Br(2)(C(18)H(15)P)(3)]·0.85C(4)H(8)O, the two independent silver(I) ions are briged by two bromide ions. One Ag(I) ion is coordinated by two triphenyl-phosphine groups with a square-planar geometry, while the second is coordinated by one triphenyl-phine group with a trigonal-planar geometry. The structure is very similar to that of the dichloro-methane solvate reported by Zhu, Huang & Zheng [Chin. J. Struct. Chem. (1994), 13, 325-327]. The tetrahydrofuran solvent molecule is disordered and was refined with a fixed occupancy of 0.85.

Poly[3,3'-diethyl-1,1'-(ethane-1,2-di-yl)diimidazolium [tetra-μ-bromido--diargentate(I)]].

Project description:The asymmetric unit of the title salt, {(C(12)H(20)N(4))[Ag(2)Br(4)]}(n), contains one-half of a substituted imidazolium cation, one Ag(+) and two Br(-) ions. The cation is completed by crystallographic inversion symmetry. The crystal structure is made up from polymeric sheets of {[AgBr(2)](-)}(n) anions extending parallel to (100). The basic building unit of the anion is a slightly distorted AgBr(4) tetra-hedron. A four- and 12-membered ring system is formed by corner sharing of the AgBr(4) tetra-hedra. The imidazolium cations are located between the anionic sheets and partly protrude into the voids defined by the 12-membered rings.

Poly[tetra-aqua-μ(3)-benzene-1,2-di-carboxyl-ato-μ(3)-bromido-penta-μ(2)-bromido-octa-μ(3)-isonicotinato-hepta-copper(I)trilanthanum(III)].

Project description:A new lanthanum(III)-copper(I) heterometallic coordination polymer, [Cu(7)La(3)Br(6)(C(6)H(4)NO(2))(8)(C(8)H(4)O(4))(H(2)O)(4)](n), has been prepared by a hydro-thermal method. Of the three La atoms in the asymmetric unit, two are eight-coordinate with bicapped trigonal-prismatic configurations; the third is nine-coordinated and has a tricapped trigonal-prismatic coordination geometry. Of the seven Cu atoms, two are two-coordinate with CuBrN and CuN(2) ligand sets, three have trigonal configurations, viz. CuBrN(2), CuBr(2)N and CuBr(3), while the remaining two adopt distorted tetra-hedral CuBr(3)N geometries. In the crystal structure, adjacent La centers are linked by isonicotinate (IN(-)) and benzene-1,2-dicarboxyl-ate ligands to form a two-dimensional La-carboxyl-ate layer in the ab plane. These layers are further inter-connected with each other by bridging [Cu(IN)(2)] motifs, leading to an unusual three-dimensional heterometallic Cu-halide-lanthanide-organic framework, with the inorganic [Cu(6)Br(6)](n) chains located in the resulting channels. Two Cu atoms are disordered over two positions, both with site occupancy factors of 0.80 and 0.20. O-H⋯O hydrogen bonding between water molecules and carboxylate O atoms helps to consolidate the crystal packing.

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.

Project description:The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57 (2) and 0.43 (2).

Di-μ(2)-bromido-bis-[bromido(η-1,2,4,5-tetra-methyl-benzene)ruthenium(II)].

Project description:The asymmetric unit of the title compound, [Ru(2)Br(4)(C(10)H(14))(2)], contains one half of the centrosymmetric mol-ecule. Each Ru center is coordinated by tetra-methyl-benzene ring in a η(6)-coordination mode, and one terminal and two bridging bromine atoms. The aromatic rings and the Ru(2)Br(2) four-membered ring form a dihedral angle of 55.99 (8)°. In the crystal structure, weak inter-molecular C-H⋯Br inter-actions link mol-ecules into chains propagated in [001].
