Catena-Poly[[di-?-bromido-dicopper(I)]bis-[?-?,?-4-(2-allyl-2H-tetra-zol-5-yl)pyridine]].

ABSTRACT: 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.

Project description:The title polymer, [Cu(2)Cl(2)(C(9)H(9)N(5))(2)](n), has been prepared by the solvothermal treatment of CuCl with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine. The crystal structure shows that the title compound is a homometallic Cu(I)-olefin coordination polymer, in which the Cu(2)Cl(2) nodes are bridged by two olefin ligands. The asymmetric unit contains one-half of the monomer, the complete monomer having twofold rotation symmetry. The coordination environment of Cu(I) is slightly distorted tetra-hedral, with coordination sites being two μ(2)-Cl atoms, one pyridine N atom of an organic ligand and one allylic double bond of a symmetry-related ligand. Each organic mol-ecule behaves as a bidentate ligand, connecting two neighboring Cu(2)Cl(2) dimers in the polymeric chain, which runs along [010].

Project description:The title compound, [CuBr(C(9)H(9)N(5))](n), has been prepared by the solvothermal treatment of CuBr with 3-(2-allyl-2H-tetra-zol-5-yl)pyridine. It is a new homometallic Cu(I) olefin coord-ination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra-zol-5-yl)pyridine ligands and bonded to one terminal Br atom each. The organic ligand acts as a bidentate ligand connecting two neighboring Cu centers through the N atom of the pyridine ring and the double bond of the allyl group. A three-dimensional structure is formed through weak Cu-Br [3.1579 (8) Å], C-H⋯Br and C-H⋯N inter-actions.

Project description:The title compound, [CuCl(C(9)H(9)N(5))](n), prepared by solvo-thermal synthesis, is a new homometallic Cu(I)-olefin coordination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra-zol-5-yl)pyridine ligands and are each bonded to one terminal Cl atom. The organic ligand acts as a bidentate ligand bridging two neighboring Cu centers through the bonds to the N atom of the pyridine ring and the double bond of the allyl group. Weak Cu⋯Cl [3.136 (8) Å), C-H⋯Cl and C-H⋯N inter-actions connect the coordination polymers into a three-dimensional structure.

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.

catena-Poly[trimethyl-phenyl-ammonium [[bromidocad-mate(II)]-μ-bromido-μ-chlorido]].

Project description:In the title salt, (C(9)H(14)N)[CdBr(2)Cl], the Cd(II) atom is five-coordinated in a trigonal-bipyramidal coordination environment. All three of the halogen sites show disorder as a result of substitution of Cl for Br or Br for Cl. Two of the three halogen atoms are involved in bridging a pair of Cd(II) atoms, generating a linear polyanionic chain motif.

μ-Bromido-dibromido-μ-hydroxido-bis-[(4S)-2-halo-6-(4-isopropyl-4,5-dihydro-oxazol-2-yl)pyridine]dicopper(II) (halo: Cl/Br = 3:1).

Project description:The crystal structure of the title complex, [Cu(2)Br(3)(OH)(C(11)H(13)Br(0.5)Cl(1.5)N(2)O)(2)], consists of two (2-halo-6-oxazolin-yl)pyridine·CuBr units bridged by a Br atom and a hydroxide group. The Cu(II) atoms are five-coordinate with an (N,N)BrCu(Br)(OH) distorted tetra-gonal-pyramidal core, and relatively short contacts to the bridging atoms (Cu-μ-OH and Cu-μ-Br). There are two symmetry-independent half-mol-ecules in the asymmetric unit, which differ only in the arrangement of the isopropyl group. The mol-ecules are located on a twofold rotation axes.

Poly[μ-chlorido-[μ(4)-5-(4-pyrid-yl)tetra-zol-ato]dicopper(I)].

Project description:The title three-dimensional coordination polymer, [Cu(2)Cl(C(6)H(4)N(5))](n), is the product of the hydro-thermal reaction of CuCl(2)·2H(2)O and 5-(4-pyrid-yl)-1H-tetra-zole (4-Hptz). The two independent Cu(I) ions are coordinated in distorted tetra-hedral and distorted trigonal coordination environments.

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.

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.

Project description:In the polymeric title complex, [MnBr2(C10H8N2)] n , the MnII ion, situated on a twofold axis of symmetry, is six-coordinated in a distorted octa-hedral coordination geometry defined by two N atoms from the chelating 2,2'-bi-pyridine ligand and four bridging Br- anions. The crystal reveals a one-dimensional Br-bridged chain along the c-axis direction with a zigzag topology. In the crystals, contacts between chains include π-π inter-actions between pyridyl rings [inter-centroid separation = 4.082 (1) Å].
