(Picolinato-?N,O)[tris(2-isopropyl-1H-imidazol-4-yl-?N)phosphane]cobalt(II) nitrate.

ABSTRACT: Single crystals of the title compound, [Co(C(6)H(4)NO(2))(C(18)H(27)N(6)P)]NO(3), were obtained from the reaction of nitrato[tris-(2-isopropyl-imidazol-4-yl)phosphane]cobalt(II) nitrate with picolinic acid in the presence of potassium tert-butoxide as base. The coordination polyhedron around the central Co(II) ion is about halfway between square-pyramidal and trigonal-bipyramidal geometry. In the structure, the nitrate counter-anion is connected by N-H?O hydrogen bonding to the complex cation. Additionally, the complex cations form one-dimensional chains along [010] by hydrogen bonding of the NH group of an imidazole ring to the picolinate group of a neighbouring complex cation.

Tris[2-(1H-imidazol-2-yl)imidazol-1-ido]cobalt(III).

Project description:In the title compound, [Co(C(6)H(5)N(4))(3)], the Co(III) atom adopts a distorted octa-hedral CoN(6) coordination geometry, arising from three N,N'-bidentate deprotonated 2,2'-biimidazole ligands. The dihedral angles between the five-membered rings of the ligands are 4.1?(2), 9.4?(2) and 10.5?(2)°. In the crystal, mol-ecules are linked by N-H?N hydrogen bonds, generating a layered network lying in (11).

Project description:In the title compound, [CoCl(2)(C(13)H(20)N(4))]·H(2)O, the Co(II) atom lies on a mirror plane and is four-coordinated by two N atoms of the imidazole ligand and two Cl atoms in a distorted tetra-hedral arrangement. The water mol-ecule participates in the formation of hydrogen bonds, resulting in a three dimensional network involving the Cl atoms and the NH groups. The terminal C atom of the ethyl group is disordered over two sites of equal occupancy.

(Salicylato)[tris-(1-methyl-1H-benz-imidazol-2-ylmeth-yl)amine]copper(II) perchlorate dimethyl-formamide disolvate.

Project description:In the title complex, [Cu(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·2C(3)H(7)NO, the Cu(II) ion is five-coordinated by four N atoms from the tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine ligand and an O atom of the monodentate salicylate ligand. The N(4)O donor set defines a coordination geometry inter-mediate between square-pyramidal and trigonal-bipyramidal. The crystal structure is stabilized by O-H⋯O inter-actions. The atoms of the aromatic ring of the salicylate ligand are disordered over two sites of equal occupancy. In addition, one of the dimethyl-formamide solvent mol-ecules is partially disordered over two positions, of approximately equal occupancy.

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

Project description:The asymmetric unit of the title compound, [Co(C(3)H(4)N(2))(6)][Co(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), contains two halves of crystallographically independent Co(II) complex cations, each assuming a distorted octa-hedral geometry, and one uncoordinated naphthalene-1,4-dicarboxyl-ate dianion. One Co(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Co(II) cation is located on a twofold rotation axis and is coordinated by three water and three imidazole mol-ecules. The uncoordinated naphthalene-1,4-dicarboxyl-ate dianion links both Co(II) complex cations via O-H?O and N-H?O hydrogen bonding. One imidazole ligand is equally disordered over two sites about a twofold rotation axis, while the coordinated N atom of the imidazole is located on the twofold rotation axis. One water O atom has site symmetry 2.
