Poly[bis-[?(2)-1,4-bis-(1H-imidazol-1-yl)butane]-dichloridonickel(II)].

ABSTRACT: The asymmetric unit of the title compound, [NiCl(2)(C(10)H(14)N(4))(2)](n), consists of one Ni(2+) ion which is located on an inversion center, one 1,4-bis-(imidazol-1-yl)butane (bimb) and one chloride ion. The Ni(2+) ion exhibits a distorted octa-hedral coordination environment defined by four N atoms from four bimb ligands in the equatorial plane and two chloride ions in axial positions. The bridging coordination mode of the bimb ligands leads to the formation of inter-penetrating square Ni(4)(bimb)(4) units that are arranged parallel to (001). The separation between the Ni atoms in these units is 13.740?(3)?Å.

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.

Project description: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)°.

The Cd(II) atoms are bridged by four bimb ligands, forming a two-dimensional (4,4) network.

Project description:In the title compound, [Mn(CHO(2))(2)(C(12)H(10)N(4))(2)](n), the Mn(II) atom and the benzene ring of the ligand lie on an inversion centers. The Mn(II) atom has an octa-hedral coordination environment composed of four N atoms from two different symmetry-related N-heterocyclic ligands forming the basal plane, and two O atoms from symmetry-related formate anions occupying the apical positions. The title compound forms a two-dimensional (4,4) net parallel to (100) with all the Mn(II) atoms lying on a plane. The crystal structure is consolidated by inter-molecular N-H?O hydrogen bonds..

Poly[[?-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dinickel(II)].

Project description:The structure of the polymeric title compound, [Ni(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), features a five-coordinate Ni(II) centre defined by four carboxyl-ate O atoms from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands and an N atom from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecule. The NO(4) coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4). These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.

Project description:The title compound, bis-[2,2'-dimethyl-3,3'-(butane-1,4-di-yl)diimidazol-1-ium] β-octa-molybdate(VI), (C(12)H(20)N(4))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4) and 1,4-bis-(2-methyl-1H-imidazol-1-yl)butane (hereafter L). The structure of the title compound consists of the β-octa-molybdate anions having a center of symmetry, and protonated [H(2)L](2+) cations, which link the β-octa-molybdate anions, generating a supra-molecular chain via hydrogen bonds.

Poly[[?(2)-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dicobalt(II)].

Project description:In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxyl-ate O atoms, derived from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene mol-ecule (1,4-bix), in a distorted square-pyramidal environment. Each end of the chdc ligand links pairs of Co(II) atoms into a paddle-wheel assembly, i.e. Co(2)(O(2)CR')(4); these are connected into rows because of the bridging nature of the chdc ligands, and the rows are further connected into a two-dimensional layer through the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions were discerned for the -CH(2)(C(6)H(4))CH(2)- residue, with the major component having a site-occupancy factor of 0.512?(9).
