Bis(cyanamide-?N)[4-(1H-imidazol-1-yl)phenol-?N]bis-(nitrato-?O)copper(II).

ABSTRACT: A pair of linear cyanamide (NCNH(2)) ligands, two monodentate 4-(1H-imidazol-1-yl)phenol (L) ligands and two nitrate anions link the Cu(II) atom into a mononuclear unit, [Cu(NO(3))(2)(C(9)H(8)N(2)O)(2)(NCNH(2))(2)]. The coordination polyhedron of the Cu atom is an elongated octa-hedron distorted by Jahn-Teller effects. Inter-molecular O-H?O, O-H?N, N-H?O and N-H?N hydrogen-bonding inter-actions link these units into a three-dimensional supra-molecular architecture.

A pair of linear cyanamide (NCNH(2)) ligands, two monodentate 4-(1H-imidazol-1-yl)phenol (L) ligands and two nitrate anions link the Cu(II) atom into a mononuclear unit, [Cu(NO(3))(2)(C(9)H(8)N(2)O)(2)(NCNH(2))(2)]. The coordination polyhedron of the Cu atom is an elongated octa-hedron distorted by Jahn-Teller effects. Inter-molecular O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link these units into a three-dimensional supra-molecular architecture. ...[more]

[Aqua-bis-(nitrato-?O)copper(II)]-?-{bis-[5-methyl-3-(pyridin-2-yl)-1H-pyrazol-4-yl]selenide}-[diaqua-(nitrato-?O)copper(II)] nitrate monohydrate.

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. ?-? 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.

Project description:In the title compound, [Ni(NO(3))(C(13)H(20)N(4))(2)]NO(3), the Ni(II) ion shows a distorted octa-hedral geometry formed by four N atoms from two bis-(2-ethyl-5-methyl-1H-imidazol-4-yl)methane ligands and two O atoms from a chelating nitrate anion. Three ethyl groups in the complex cation and the O atoms of the uncoordinated nitrate anion are disordered over two sets of positions [occupancy ratios of 0.52 (3):0.48 (3) and 0.63 (3):0.37 (3), respectively]. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the complex cations into a zigzag chain along [010] and further N-H⋯O hydrogen bonds between the chains and the uncoordinated nitrate anions lead to layers parallel to (100).

catena-Poly[copper(I)-bis-[?-3-(1H-imidazol-2-yl)pyridine]-copper(I)-di-?-iodido].

Project description:The title polymeric compound, [Cu(2)I(2)(C(8)H(7)N(3))(2)](n) [C(8)H(7)N(3) = 3-(1H-imidazol-2-yl)pyridine (HIPy), where HIPy comes from the in situ deca-rboxylation of 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarb-oxy-lic acid (H(3)PyIDC)], was obtained under solvo-thermal conditions. Each Cu(I) cation is in a distorted tetra-hedral coordination environment defined by two iodide anions and two nitro-gen atoms from two individual HIPy ligands. Two Cu(I) atoms are connected by two HIPy ligands to form a dimer and these dimers are further bridged through the iodide atoms, leading to a chain structure extending parallel to [100]. Moreover, inter-molecular N-H?I hydrogen bonds and weak ?-? stacking inter-actions [centroid?centroid distances of 3.809?(4)?Å, an inter-planar separation of 3.345?(3)?Å and a ring slippage of 1.822?Å] between pyridyl rings link the chains into a two-dimensional supra-molecular network in the ac plane.
