Aqua-bis-(1-methyl-1H-imidazole-?N)bis-(nitrato-?O)copper(II).

ABSTRACT: The title complex mol-ecule, [Cu(NO(3))(2)(C(4)H(6)N(2))(2)(H(2)O)], has crystallographically imposed twofold symmetry. The Cu(II) atom displays a distorted square-pyramidal CuN(2)O(3) coordination geometry. In the crystal, inter-molecular O-H?O hydrogen bonds between the coordinated water mol-ecule and the nitrate anions form chains parallel to the c axis.

Project description:In the title binuclear complex, [Cu2(NO3)3(C18H16N6Se)(H2O)3]NO3·H2O, the Cu(II) ions are penta-coordinated in a tetra-gonal-pyramidal geometry. In both cases, the equatorial planes are formed by a chelating pyrazole-pyridine group, a water mol-ecule and a nitrate O atom, whereas the apical positions are occupied by a water mol-ecule for one Cu(II) ion and a nitrate O atom for the other. The organic selenide ligand adopts a trans configuration with respect to the C-Se-C plane. Numerous inter-molecular O-H⋯O and N-H⋯O hydrogen bonds between the coordinating and lattice water mol-ecules, nitrate anions and pyrazole groups are observed. π-π stacking inter-actions between the pyridine rings [averaged centroid-centroid distance = 3.652 (5) Å] are also present. The lattice water molecule is equally disordered over two sets of sites.

Aqua-bis(1H-imidazole-κN)bis-(4-methyl-benzoato-κO,O')cadmium(II).

Project description:In the title compound, [Cd(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Cd(II) atom is coordinated by four carboxyl-ate O atoms from two bidentate chelating 4-methyl-benzoate ligands, two N atoms from two imidazole ligands and one water mol-ecule in a distorted penta-gonal bipyramidal geometry. Inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the carboxyl-ate O atoms of 4-methyl-benzoate lead to an infinite chain. These chains are further self-assembled into a two-dimensional layer through N-H⋯O hydrogen bonds between the imidazole ligands and carboxyl-ate groups. One of the imidazole ligands is disordered over two positions with site-occupancy factors of 0.737 (4) and 0.263 (4).

Aqua-bis(1H-imidazole-κN)bis-(4-methyl-benzoato)-κO;κO,O'-nickel(II).

Project description:In the mononuclear title compound, [Ni(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Ni(II) atom is coordinated by three carboxylate O atoms (from a bidentate 4-methyl-benzoate ligand and a monodentate 4-methyl-benzoate ligand), two N atoms (from two imidazole ligands) and a water mol-ecule in an octa-hedral geometry. Inter-molecular O-H⋯O hydrogen-bonding inter-actions lead to infinite chains, which are further self-assembled into a supra-molecular network through inter-molecular N-H⋯O hydrogen-bonding inter-actions and π-π stacking [centroid-centroid distance = 3.717 (2) Å].

trans-Bis(nitrato-?O)tetra-kis-(1-vinyl-1H-imidazole-?N(3))copper(II).

Project description:In the title compound, [Cu(NO(3))(2)(C(5)H(6)N(2))(4)], the Cu(II) ion is located on an inversion centre. It features a Jahn-Teller-distorted octa-hedral coordination geometry, defined by four N atoms of four 1-vinyl-imidazole ligands in the equatorial plane and two nitrate O atoms in the axial positions. The nitrate anion is disordered over two sets of sites in a 0.801?(6):0.199?(6) ratio. In the crystal, the complex mol-ecules are linked by weak inter-molecular C-H?O and C-H?? inter-actions.

Tetra-aqua-bis-(2-methyl-1H-imidazole-?N)cobalt(II) naphthalene-1,5-disulfonate.

Project description:In the title complex, [Co(C(4)H(6)N(2))(2)(H(2)O)(4)](C(10)H(6)O(6)S(2)), the cation and anion both reside on crystallographic inversion centers, such that the asymmetric unit comprises one half cation and one half anion. The central Co(II) ion is coordinated by four water mol-ecules and two 2-methyl-imidazole ligands, resulting in a trans-octa-hedral coordination geometry. The existence of strong N-H?O and O-H?O hydrogen-bonding inter-actions gives rise to a three-dimensional structure.

Project description: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].

Bis-(2-methyl-1H-imidazole-?N)bis[2-(naphthalen-2-yl)acetato-?O]copper(II).

Project description:In the crystal structure of the title compound, [Cu(C(12)H(9)O(2))(2)(C(4)H(6)N(2))(2)], the Cu(II) cations are square-planar coordinated by two 1-naphthyl-acetate anions and two 2-methyl-imidazole ligands into discrete complexes that are located on centres of inversion. These complexes are linked into chains parallel to [010] by inter-molecular N-H?O hydrogen bonding between the N-H H atom of the 2-methyl-imidazole ligands and the carboxyl-ate O atoms that are not involved in metal coordination.

[Di-aqua-sesqui(nitrato-κO)hemi(perchlorato-κO)copper(II)]-μ-{bis-[5-methyl-3-(pyridin-2-yl)-1H-pyrazol-4-yl] selenide}-[tri-aqua-(perchlorato-κO)copper(II)] nitrate monohydrate.

Project description:In the binuclear title complex, [Cu2(ClO4)1.5(NO3)1.5(C18H16N6Se)(H2O)5]NO3·H2O, both Cu(II) ions are hexa-coordinated by O and N atoms, thus forming axially elongated CuO4N2 octa-hedra. The equatorial plane of each octa-hedron is formed by one chelating pyrazole-pyridine fragment of the organic ligand and two water mol-ecules. The axial positions in one octa-hedron are occupied by a water mol-ecule and a monodentately coordinated perchlorate anion, while those in the other are occupied by a nitrate anion and a disordered perchlorate/nitrate anion with equal site occupancy. The pyrazole-pyridine units of the organic selenide are trans-oriented to each other with a C-Se-C angle of 96.01 (14)°. In the crystal, uncoordinated nitrate anions and the coordinating water mol-ecules are involved in O-H⋯O and N-H⋯O hydrogen bonds, forming a bridge between the pyrazole group and the coordinating water mol-ecules. Further O-H⋯O hydrogen bonds between the complex mol-ecules and a π-π stacking inter-action with a centroid-centroid distance of 3.834 (4) Å are also observed.

Project description:In the crystal structure of the title compound, [Cu(C(12)H(9)O(2))(2)(C(4)H(6)N(2))(2)]·H(2)O, the Cu(II) atom is coordinated by two 2-(naphthalen-1-yl)acetate anions and two 1-methyl-imidazole ligands, giving monomeric complexes with a square-planar coordination environment. Two complex mol-ecules and two water mol-ecules form a centrosymmetric ring system via O-H?O hydrogen bonds.

catena-Poly[[[aqua-bis(1H-imidazole-κN)copper(II)]-μ-naphthalene-1,4-dicarboxyl-ato-κO:O] dihydrate].

Project description:In the title compound, {[Cu(C(12)H(6)O(4))(C(3)H(4)N(2))(2)(H(2)O)]·2H(2)O}(n), the Cu(II) cation is coordinated by two naphthalene-1,4-dicarboxyl-ate (naph) dianions, two imidazole mol-ecules and one water mol-ecule in a distorted square-pyramidal geometry. The Cu-O bond distance in the apical direction is 0.509 (3) Å longer than the mean Cu-O bond distance in the basal plane. The naph dianion bridges two Cu(II) cations, forming a one-dimensional polymeric chain. The coordinated water mol-ecule is hydrogen-bonded to the carboxylate groups and imidazole ligands of adjacent polymeric chains, forming a three-dimensional supra-molecular structure. No π-π stacking is observed in the crystal structure. One solvent water molecule is disordered equally over two positions.
