Catena-Poly[[dichloridozinc(II)]-?-1,4-bis-(1H-imidazol-1-yl)benzene].

ABSTRACT: In the title one-dimensional coordination polymer, [ZnCl(2)(C(12)H(10)N(4))](n), the Zn(II) atom (site symmetry 2) is coordinated by two chloride ions and two 1,4-bis-(imidazol-1-yl)benzene ligands, generating a distorted tetra-hedral ZnCl(2)N(2) geometry for the metal ion. The bridging ligand, which is completed by crystallographic inversion symmetry, links the Zn(II) atoms into zigzag chains propagating in [101]. Within the ligand, the dihedral angle between the central benzene ring and terminal imidazole ring is 27.82?(13)°.

Project description:In the crystal structure of the title coordination polymer/co-crystal, {[ZnCl(2)(C(18)H(18)N(4))]·C(18)H(18)N(4)}(n), the tetrahedrally coordinated Zn(II) ions are linked by the N-heterocycle into a linear chain. Another N-heterocycle present is not coordinated to the metal atom but inter-acts with the chain through N-H?N and N-H?Cl hydrogen bonds. The butyl chain of the uncoordinated ligand is disordered over three positions in a 0.511?(4):0.289?(5):0.200?(5) ratio.

catena-Poly[[dichloridozinc(II)]-μ-1,4-bis-(3-pyridylmeth-yl)piperazine].

Project description:In the title compound, [ZnCl(2)(C(16)H(20)N(4))](n), tetra-hedrally coordinated divalent Zn atoms are ligated by two Cl atoms and two N-donor atoms from two 1,4-bis-(3-pyridylmeth-yl)-piperazine (3-bpmp) ligands. The tethering 3-bpmp ligands promote the formation of [ZnCl(2)(3-bpmp)](n) chains situated parallel to (02). These chains aggregate via C-H⋯Cl inter-actions to form supra-molecular layers, which in turn stack to construct the three-dimensional crystal structure.

Project description:In the title coordination polymer, [Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O)](n), the Cd(II) atom has a NO(6) donor set and is coord-inated by five carboxyl-ate O atoms from three different 5-methyl-1,3-phenyl-enediacetate (pda(2-)) anions, one O atom from a water mol-ecule and one N atom from a 1,4-bis-(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta-gonal-bipyramidal geometry. Each pda(2-) anion acts as a μ(3)-bridge, linking Cd(II) atoms to form one-dimensional slabs extending parallel to [010]. In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

The bzb mol-ecule acts as a bridging ligand to connect the metal atoms into a chain propagating in [1[Formula: see text][Formula: see text]]. The dihedral angle between the benzimidazole ring and the central benzene ring in the ligand is 38.16 (9)°. In the crystal, O-H⋯O hydrogen bonds crosslink the chains into (010) sheets.
