چکیده
In the title compound, [Cu(C(6)H(6)N(4))(2)](C(9)H(5)N(4)O)(2), the Cu(2+) ion (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole (H(2)biim) ligands, generating a square-planar CuN(4) geometry. The dihedral angle between the aromatic rings in the ligand is 0.70 (9)°. In the polynitrile 1,1,3,3-tetra-cyano-2-eth-oxy-propenide (tcnoet) anion, the C-N, C-C and C-O bond lengths indicate extensive electronic delocalization. An alternative description for the metal-ion geometry is an extremely distorted CuN(6) octa-hedron, with two N-bonded tcnoet anions completing the coordination. In the crystal, the components are linked by N-H⋯N and C-H⋯N inter-actions.

In the title copper(II) salt, [Cu(C(6)H(6)N(4))(2)(C(2)H(6)OS)(2)](BF(4))(2), the Jahn-Teller distorted octa-hedral coordination sphere of copper is formed from four 2,2'-bi-1H-imidazole N atoms and two dimethyl sulfoxide O atoms. The Cu atom lies on a center of inversion. N-H⋯O and N-H⋯F hydrogen bonds give rise to a one-dimensional structure. The BF(4) (-) anion is disordered over two sites i...

In title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(4))(2)], the Cu(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two weakly bonded 4-methyl-benzoate anions, resulting in a strongly elongated trans-CuO(2)N(4) octa-hedral geometry. In the crystal, adjacent mol-ecules are linked via pairs of N-H⋯O hydrogen bonds into chains propagating in [010].

The dinuclear title compound, [Co(2)(C(10)H(8)N(4)O(4))(2)(H(2)O)(4)]·6H(2)O, lies about an inversion centre. Each Co(II) atom is six-coordinated by two water mol-ecules, two carboxyl-ate O atoms and two N atoms of two symmetry-related 2,2'-bi-1H-imidazole-1,1'-diacetate (L(2-)) ligands in a slightly distorted octa-hedral geometry. Mol-ecules are linked into a three-dimensional framework via O-...
