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 ?(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].

catena-Poly[[bromidocopper(I)]-?-?,?-3-(2-allyl-2H-tetra-zol-5-yl)pyridine].

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.

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[potassium-di-?-aqua-?-4-(5-tetra-zolio)pyridine].

Project description:The title compound, [K(C(6)H(4)N(5))(H(2)O)(2)](n), was synthesized by hydro-thermal reaction of KOH with 4-(5-tetra-zolio)pyridine. The K atom has a distorted octa-hedral coordination environment and is coordinated by two axial N atoms from the organic ligand and by four water mol-ecules in the equatorial plane. The mol-ecules as a whole are located on crystallographic mirror planes; the K atom is also located on an inversion center. Both the water mol-ecules and the organic ligands act as bridges to link symmetrically the adjacent K atoms into polymeric chains parallel to the c axis. O-H?N hydrogen bonds involving the water O atoms and aromatic ?-? inter-actions [centroid-centroid distance 3.80?(2)?Å] between the pyridine and tetra-zole rings build up an infinite three-dimensional network.

Project description:The title compound, [Hg5Br10(C7H8N2O)2] n , contains two ?3-bridging Br atoms, six ?2-bridging Br atoms and two terminal Br atoms. One Hg(II) atom, lying on an inversion center, adopts a distorted octa-hedral geometry defined by six Br atoms. Two Hg(II) atoms adopt a distorted square-pyramidal geometry by five Br atoms and the other two Hg(II) atoms have a distorted tetra-hedral geometry by two N atoms from a chelating O-methyl pyridine-2-carboximidate ligand and two Br atoms. The Br atoms link the Hg(II) atoms into a ribbon structure along [100].

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.

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

Project description: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.

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.

catena-Poly[[(N,N-di-methyl-cyanamide-κN)lithium]-μ3-bromido].

Project description:The title complex, [LiBr(C3H6N2)] n , is the unexpected product of a reaction beteween (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso-propyl-phen-yl), Me2NCN and CuBr. The compound is a one-dimensional polymer with a step structure derived from the association of inversion dimers, formed by bromido ligands bridging two Li(+) cations, each of which carries a di-methyl-cyanamide ligand. The planar (LiBr)2 unit of the polymer core has a regular rhombic shape [Li-Br-Li 77.55 (16)° and Br-Li-Br 102.45 (16)°]. These (LiBr·NCNMe2)2 dimers represent the repeat unit of a polymer system propagated by additional Br-Li and Li-Br bonds generating an infinite step structure along the a-axis direction.
