چکیده
The crystal structure of the title polymeric complex, [CuCl(2)(C(3)H(6)N(4)O)(2)](n), was obtained by the Rietveld refinement from laboratory X-ray powder diffraction data collected at room temperature. The unique Cu(II) ion lies on an inversion center and is in a slightly distorted octa-hedral coordination environment. In the hydroxy-ethyl group, all H atoms, the O atom and its attached C atom are disordered over two positions; the site occupancy factors are ca 0.6 and 0.4. The OH group is involved in an intra-molecular O-H⋯N hydrogen bond.

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

The asymmetric unit of the title compound, [CoCl(2)(C(3)H(6)N(4))](n), contains two Co atoms, both lying on inversion centres, two Cl atoms and one 1,5-dimethyl-tetra-zole ligand. The coordination polyhedra of both Co atoms adopt flattened octa-hedral geometry, with two N atoms from two ligands in axial positions and four Cl atoms in equatorial sites. Neighbouring Co atoms are linked together v...

In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain...

The title compound, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), is a coordination polymer with the Cd(II) centre located on a twofold rotation axis. The Cd(II) centre assumes a distorted octa-hedral geometry. The thio-cyanate anions function as bridging ligands between the Cd(II) centres, leading to a chain-like arrangement expanding along [001].

In the crystal structure of the title complex, [Cd(NCS)(2)(C(7)H(5)ClN(4))(2)](n), the Cd(II) atom lies on a crystallographic inversion center and assumes a distorted octa-hedral geometry. The 2-chloro-6-(1H-1,2,4-triazol-1-yl)pyridine mol-ecule acts as a terminal ligand. The thio-cyanate ligands function as μ(1,3)-bridging units connecting adjacent Cd(II) atoms with a separation of 5.7525 (11)...
