Diaqua-bis-(1H-imidazole-4-carboxyl-ato-?(2)N(3),O)cobalt(II).

ABSTRACT: In the title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Co(II) ion is located on a twofold rotation axis and shows a distorted octa-hedral coordination configuration, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions. In the crystal, O-H?O and N-H?O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network. ?-? stacking inter-actions between the imidazole rings [centroid-centroid distances = 3.4914?(15) and 3.6167?(15)?Å] further stabilize the crystal structure.

Diaqua-[5,5'-dicarb-oxy-2,2'-(ethane-1,2-di-yl)bis-(1H-imidazole-4-carboxyl-ato)]cobalt(II).

Project description:In the title complex, [Co(C(12)H(8)N(4)O(8))(H(2)O)(2)], the Co(II) atom is coordinated by two N and two O atoms of the tetra-dentate 5,5'-dicarb-oxy-2,2'-(ethane-1,2-di-yl)bis-(1H-imidazole-4-carboxy-l-ate) anion. The slightly distorted octa-hedral coordination environment is completed by the O atoms of two water mol-ecules in axial positions. An intra-molecular O-H?O hydrogen bond between the carb-oxy and carboxyl-ate groups stabilizes the mol-ecular configuration. Adjacent mol-ecules are linked through O-H?O and N-H?O hydrogen bonds between the carb-oxy/carboxyl-ate groups, water mol-ecules and imidazole fragments into a three-dimensional network.

Project description:In the title complex, [Co(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·3.5H(2)O, the Co(II) cation is six-coordinated by two H(2)pimda(-) ligands (H(3)pimda is 2-propyl-1H-imidazole-4,5-carboxylic acid) and two water mol-ecules in a distorted octa-hedral environment. The crystal structures features a three-dimensional network stabilized by extensive O-H?O and N-H?O hydrogen bonds. The propyl groups of the ligands are disordered over two sets of sites with refined occupancies of 0.673?(8):0.327?(8) and 0.621?(17):0.379?(17). One of the water mol-ecules is located on a site with half-occupancy.

Diaqua-bis-(1H-imidazole-4-carboxyl-ato-κN,O)zinc.

Project description:In the title compound, [Zn(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Zn(II) ion is situated on a twofold rotation axis and exhibits a distorted octa-hedral coordination configuration. The equatorial plane contains two cis-oriented bidentate 1H-imidazole-4-carboxyl-ate ligands and the axial positions are occupied by two coordinated water mol-ecules. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network. There are π-π inter-actions between the imidazole rings, with a centroid-to-centroid distance of 3.504 (3) Å.

Bis(1H-imidazole-?N)bis-(2-oxidopyridinium-3-carboxyl-ato-?O,O)cobalt(II).

Project description:In the mol-ecule of the title Co(II) complex, [Co(C(6)H(4)NO(3))(2)(C(3)H(4)N(2))(2)], the Co(II) atom is located on a twofold rotation axis and chelated by two oxidopyridiniumcarboxyl-ate anions and further cis-coordinated by two imidazole ligands in a distorted octa-hedral geometry. The shorter C-O bond distance of 1.260?(2)?Å suggests electron delocalization between the oxido group and the pyridinium ring. The uncoordinated carboxyl-ate O atom links with the imidazole and pyridinium rings of adjacent mol-ecules via N-H?O hydrogen bonding. Weak C-H?O hydrogen bonding is also present in the crystal structure.
