Tris(2,2'-bi-1H-imidazole-?N,N)-nickel(II) dinitrate N,N-dimethyl-formamide monosolvate.

ABSTRACT: 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 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.

Project description:In the title compound, [Ni(C(18)H(18)N(2)O(4))]·C(3)H(7)NO, the central Ni(II) atom is in a square-planar O(2)N(2) coordination environment. The planar Ni-salen moieties (r.m.s. deviation for the plane through the conjugated part of the Ni-salen group = 0.07 Å) form parallel stacks in the a-axis direction, with alternating Ni⋯Ni separations of 3.5339 (7) and 3.6165 (7) Å. In the crystal, there are weak inter-molecular C-H⋯O inter-actions involving the dimethyl-formamide O and phenolate O atoms.

Poly[(dimethyl-formamide)(?(4)-2,2'-sulfanediyldibenzoato)nickel(II)].

Project description:The title centrosymmetric dinuclear Ni(II) complex, [Ni(C(14)H(8)O(4)S)(C(3)H(7)NO)](n), was prepared via reaction of Ni(NO(3))(2)·6H(2)O and thio-salicylic acid, with H(2)O and dimethyl-formamide (DMF) as the mixed solvent. The central Ni(II) ion is five-coordinated by five O atoms from DMF and from the carboxyl-ate groups of the organic ligand. The symmetry-related coordination polyhedra inter-link into centrosymmetric dimeric units and these, in turn, are linked into infinite chains propagating parallel to [100].

catena-Poly[[(diiodidocadmium)-μ-{1-[(1H-benzimidazol-2-yl)meth-yl]-1H-imidazole-κN:N'}] N,N-dimethyl-formamide monosolvate].

Project description:In the title complex, {[CdI(2)(C(11)H(10)N(4))]·C(3)H(7)NO}(n), the Cd(II) ion is four-coordinated by two N atoms from two 1-[(1H-benzimidazol-1-yl)meth-yl]-1H-imidazole (bmi) ligands and by two terminal I(-) anions in a distorted tetra-hedral geometry. One of the two I(-) anions is disordered over two sets of sites, with refined occupancies of 0.66 (5) and 0.34 (5). The Cd(II) ions are bridged by bmi ligands, leading to the formation of a chain along [001]. Dimethyl-formamide solvent mol-ecules are located between these chains. Classical N-H⋯O hydrogen bonding between the bmi ligands and the solvent mol-ecules leads to a consolidation of the structure.

(Dimethyl-formamide-κO)(2-hy-droxy-benzoato-κO,O)[tris-(1-methyl-1H-benzimidazol-2-ylmethyl-κN)amine-κN]manganese(II) perchlorate dimethyl-formamide monosolvate.

Project description:In the title complex, [Mn(C(7)H(5)O(3))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is coordinated in a slightly distorted monocapped trigonal-prismatic geometry. The tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand coordinates in a tetra-dentate mode and the coordination is completed by a bis-chelating salicylate ligand and a dimethyl-formamide ligand. The hy-droxy group and the ortho H atoms of the salicylate ligand were refined as disordered over two sites with occupancies of 0.581 (8) and 0.419 (8). Both disorder components of the hy-droxy group form intra-molecular O-H⋯O hydrogen bonds.

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.

Hexakis(1H-imidazole-?N)nickel(II) bis-(2,4-dibromo-6-formyl-phenolate) N,N-dimethyl-formamide disolvate.

Project description:In the cation of the title compound, [Ni(C(3)H(4)N(2))(6)](C(7)H(3)Br(2)O(2))(2)·2C(3)H(7)NO, the Ni(II) ion lies on an inversion center and is coordinated in a slightly distorted octa-hedral environment by six N atoms from six imidazole ligands. In the crystal structure, cations, anions and solvent mol-ecules are linked by inter-molecular N-H?O hydrogen bonds into one-dimensional chains along [010]. In addition, the crystal structure is stabilized by weak C-H?O and C-H?N hydrogen bonds.

Hexakis(1H-imidazole-?N)nickel(II) triaqua-tris(1H-imidazole-?N)nickel(II) bis-(naphthalene-1,4-dicarboxyl-ate).

Project description:The crystal structure of the title compound, [Ni(C(3)H(4)N(2))(6)][Ni(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), contains uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Ni(II) complex cations, both assuming distorted octa-hedral geometries. One Ni(II) ion is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Ni(II) ion is located on a twofold rotation axis and is coordinated by three water mol-ecules and three imidazole mol-ecules in a mer-NiN(3)O(3) arrangement. The naphthalene-dicarboxyl-ate dianion links both Ni(II) complex cations via O-H?O and N-H?O hydrogen bonding, but no ?-? stacking is observed between aromatic rings in the crystal structure. One imidazole ligand is equally disordered over two sites about a twofold rotation axis; one N atom and one water O atom have site symmetry 2.

Project description: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 in a 0.671 (10):0.329 (10) ratio.
