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

ABSTRACT: 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.

Project description:In the title complex, [Zn(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·3.5H(2)O, the Zn(II) ion is coordinated by two N,O-bidentate H(2)pimda ligands (H(3)pimda = 2-propyl-1H-imidazole-4,5-dicarb-oxy-lic acid) and two water mol-ecules in a distorted octa-hedral environment.

Intra-molecular O-H⋯O hydrogen bonds between the carboxyl groups are also observed. The propyl groups of the two H(2)pimda ligands are disordered each over two sites, with occupancy factors of 0.752 (5):0.248 (5) and 0.519 (7):0.481 (7). One of the water mol-ecules is half-occupied.

Diaqua-bis-(4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ato-κN,O)cadmium dihydrate.

Project description:The asymmetric unit of the title compound, [Cd(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, consists of one Cd(II) ion, one 4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ate anion, one coordinated water mol-ecule and one lattice water mol-ecule. The Cd(II) ion lies on a twofold axis, and is hexa-coordinated by four O atoms from water mol-ecules and carboxyl-ate groups and two N atoms from two imidazole rings, in a distorted octa-hedral arrangement. An extensive framework of N-H⋯O and O-H⋯O hydrogen bonds with the participation of coordinated and free water mol-ecules is found in the crystal structure, which contributes to the formation of a three-dimensional structure.

Project description:In the crystal structure of the title compound, [Zn(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Zn(II) atom is coordinated by two N,O-bidentate 2-propyl-1H-imidazole-4,5-dicarboxyl-ate anions and two water mol-ecules in a distorted octa-hedral environment.

Project description:In the crystal structure of the title compound, [Zn(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·3H(2)O, the Zn(II) ion, located an inversion center, is N,O-chelated by two 5-carb-oxy-2-ethyl-1H-imidazole-4-carboxyl-ate anions and further coordinated by two water mol-ecules in a distorted octa-hedral geometry.

An extensive inter-molecular N-H?O and O-H?O hydrogen-bonded network exists in the crystal structure. One disordered lattice water mol-ecule is half-occupied and is located close to an inversion center.

Project description:In the title complex, [Cd(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·3.5H(2)O, the Cd(II) is coordinated by two water mol-ecules and N,O-chelated by two 5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ate anions in a distorted octa-hedral geometry.
