Tetra-kis(1H-benzimidazole-?N)(nitrato-?O)copper(II) nitrate.

ABSTRACT: In the title salt, [Cu(NO(3))(C(7)H(6)N(2))(4)]NO(3), one nitrate anion is coordinated to the Cu(II) atom, which is also coordinated by the N atoms of four N-heterocycles. The geometry at the metal atom is a square pyramid in which the O atom of the anion occupies the apical position [Cu-O = 2.468?(5) and 2.590?(7)?Å in the two independent formula units]. The cation lies on a twofold rotation axis; the coordinated nitrate anion is also disordered about this symmetry element. The lattice anion is also disordered about a twofold rotation axis. In the crystal, the cations are linked to the coordinated and free anions by N-H?O hydrogen bonds.

Project description:The title compound, [Cd(NO(3))(C(5)H(8)N(2))(4)]NO(3), was prepared by reaction of cadmium nitrate and 3,5-dimethyl-pyrazole in ethanol solution. The Cd atom adopts a distorted cis-CdO(2)N(4) octa-hedral geometry involving four dimethylpyrazole molecules and one bidentate nitrate anion.

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.

Hexa-?-chlorido-?(4)-oxido-tetra-kis-({1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-?N}copper(II)).

Project description:The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and through three separate chloride-ion bridges. The fifth coord-ination position, located on the central Cu-O axis on the outside of the cluster, is occupied by an N atom of the mono-dentate 1-(pyridin-2-ylmeth-yl)-1H-benzimidazole ligand. The resulting coordination geometry of the metal ion is a distorted trigonal bipyramid with the O and N atoms in the axial positions. The dihedral angle between the benzimidazole ring system and the pendant pyridine ring is 61.0?(2)°.

Bis(nitrato-?O)tetra-kis-[1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one]copper(II).

Project description:In the title complex, [Cu(NO(3))(2)(C(11)H(11)N(3)O)(4)], the Cu(II) atom is situated on a centre of inversion and is coordinated by two O atoms from two nitrate anions and four N atoms from four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted octa-hedral geometry. Weak inter-molecular C-H?O and C-H?N hydrogen bonds result in a supra-molecular layer parallel to (101). These layers are connected by ?-? inter-actions between the benzene rings [centroid-centroid distance = 3.891?(2)?Å].

The Ni(2+) centre is chelated by three bidentate 2,2'-bi-1H-benzimidazole mol-ecules in a distorted octa-hedral coordination. N-H⋯O hydrogen bonds consolidate the building units into a framework structure.

Project description:In the title compound, [Ca(NO(3))(C(34)H(32)N(10))]NO(3)·3CH(4)O, the Ca(II) ion is coordinated by six N atoms of the EDTB ligand {EDTB is N,N,N',N'-tetra-kis[(2-benzimidazol-yl)meth-yl]-1,2-ethanediamine} and two O atoms from the nitrate ligand, to form a distorted dodeca-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds, which link the constituent units into a three-dimensional network. The uncoordinated nitrate anion is disordered over two sites, with fixed occupancies of 0.77 and 0.23.

Project description:In the title compound, [Cu(NO(3))(2)(C(8)H(9)N(3))(2)], the Cu(II) atom, lying on an inversion center, has a distorted octa-hedral coordination environment defined by four N atoms from two chelating 2-amino-methyl-1H-benzimidazole ligands and two O atoms from two monodentate nitrate anions.

cyclo-Tetra-μ-malato-κO,O',O'':O'''-tetra-kis[bis-(1H-benzimidazole-κN)cobalt(II)] eicosa-hydrate.

Project description:The title compound, [Co(4)(C(4)H(4)O(5))(4)(C(7)H(6)N(2))(8)]·20H(2)O, consists of tetra-nuclear Co(II) complexes and disordered uncoordinated water mol-ecules. The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a distorted octa-hedral coordination geometry. The tridentate malate dianion chelates the Co(II) ion, and the chelate six- and five-membered rings show half-chair and envelope configurations, respectively. A face-to-face separation of 3.494 (9) Å between parallel benzimidazole ligands indicates the existence of π-π stacking between adjacent complexes. The crystal structure also involves N-H⋯O and O-H⋯O hydrogen bonds.

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