Tris(2,2'-bi-1H-imidazole-?N,N)cobalt(II) hydrogen phosphate.

ABSTRACT: The title compound, [Co(C(6)H(6)N(4))(3)]HPO(4), was synthesized under hydro-thermal conditions. In the cation, the Co(II) atom is octa-hedrally coordinated by six N atoms from three 2,2'-bi-1H-imidazole ligands [Co-N bond lengths are in the range 2.084?(5)-2.133?(6)?Å]. Inter-molecular N-H?O hydrogen bonds form an extensive hydrogen-bonding network, which links cations and anions into a three-dimensional crystal structure.

One Co(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Co(II) cation is located on a twofold rotation axis and is coordinated by three water and three imidazole mol-ecules. The uncoordinated naphthalene-1,4-dicarboxyl-ate dianion links both Co(II) complex cations via O-H?O and N-H?O hydrogen bonding. One imidazole ligand is equally disordered over two sites about a twofold rotation axis, while the coordinated N atom of the imidazole is located on the twofold rotation axis. One water O atom has site symmetry 2.

Project description:The reaction of nickel salts and 4,4'-bipyridine with 2,2'-bi-imidazole (H(2)biim) yielded the title complex, [Ni(C(6)H(6)N(4))(3)](NO(3))(2)·C(3)H(7)NO. The Ni(II) atom is chelated by three H(2)biim ligands in a distorted octa-hedral coordination geometry. The two nitrate anions and one dimethyl-formamide (DMF) mol-ecule are not coordinated. The compound has a three-dimensional structure, formed by extensive hydrogen bonding between [Ni(H(2)biim)(3)](2+) cations and nitrate anions, each nitrate anion forming hydrogen bonds with an R(1) (2)(4) motif. The DMF molecule is disordered over three sets of sites, with occupancy ratios of 0.341?(16):0.350?(17):0.309?(19).

Project description: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.

Project description:In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27?(4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation. The mol-ecules are linked into a three-dimensional framework with a parallel laminated construction via O-H?N and C-H?O inter-actions.

Project description: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.
