Aqua-tris(1H-benzimidazole-?N)(dichloro-acetato-?O)copper(II) dichloro-acetate dihydrate.

ABSTRACT: The title compound, [Cu(C(2)HCl(2)O(2))(C(7)H(6)N(2))(3)(H(2)O)]C(2)HCl(2)O(2)·2H(2)O, was prepared by reaction of copper(II) 2,2-dichloro-acetic acid and benzimidazole in ethanol solution. The compound shows a regular trigonal-bipyramidal stereochemistry. The Cu(II) centre possesses a five-coordinated environment, coordinated by three N atoms from the three benzimidazole ligands and two O atoms, one from the dichloro-acetate ligand and the other from the coordinated water mol-ecule. The mol-ecular structure and packing are stabilized by O-H?O and N-H?O hydrogen bonds. The Cl atoms are disordered over two sites, with relative occupancies 0.67?(3) and 0.33?(3).

Project description:In the title compound, [Co(2)(C(2)H(3)O(2))(4)(C(7)H(6)N(2))(4)(H(2)O)], the half-mol-ecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full mol-ecule.

The compound features intra-molecular O-H?O hydrogen bonds between the non-bridging acetate groups and the bridging water mol-ecule, and inter-molecular N-H?O hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the mol-ecular packing in the crystal structure.

Project description:In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichloro-acetate ligand occupies the apical positon [Cu-O = 2.152 (3) Å]. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing also exhibits weak inter-molecular C-H⋯O hydrogen bonds, π-π inter-actions [centroid-centroid distance = 3.734 (2) Å] and short inter-molecular Cl⋯Cl contacts [3.306 (2) and 3.278 (2) Å].

Bis[2-(pyrrolidin-2-yl)-1H-benzimidazole-?N,N]copper(II) dinitrate dihydrate.

Project description:In the title compound, [Cu(C(11)H(13)N(3))(2)](NO(3))(2)·2H(2)O, synthesized by hydro-thermal reaction of Cu(NO(3))(2) and racemic 2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole, the Cu(II) atom lies on an inversion centre. The distorted octa-hedral Cu(II) environment contains two planar trans-related N,N-chelating 2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole ligands in the equatorial plane and two monodentate nitrate anions, which are in weak inter-action with the Cu atom, in the axial positions. The two benzimidazole ligands have opposite configurations (R/S and S/R) and compound is a meso complex. In the crystal, N-H?O and O-H?O hydrogen bonds generate an infinite three-dimensional network. One methylene group of the pyrrolidine ring is disordered over two position with a 0.56?(3):0.44?(3) occupancy.

Aqua-bis-(3,5-dimethyl-1H-pyrazole-?N)(oxydiacetato-?O,O',O'')copper(II) dihydrate.

Project description:In the title compound, [Cu(C(4)H(4)O(5))(C(5)H(8)N(2))(2)(H(2)O)]·2H(2)O, the Cu(II) cation assumes a distorted octa-hedral coordination geometry formed by two 3,5-dimethyl-1H-pyrazole ligands, one oxydiacetate (ODA) dianion and one coordinated water mol-ecule. The tridentate ODA ligand chelates to the Cu cation in a facial configuration with a longer Cu-O bond [2.597?(3)?Å], and both chelating rings display envelope conformations. In the mol-ecule, the two pyrazole rings are twisted with respect to each other at a dihedral angle of 57.5?(3)°. Extensive inter-molecular O-H?O and N-H?O hydrogen bonding is present in the crystal structure.

catena-Poly[[[aqua-bis(1H-imidazole-?N)copper(II)]-?-naphthalene-1,4-dicarboxyl-ato-?O: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 ?-? stacking is observed in the crystal structure. One solvent water molecule is disordered equally over two positions.
