Diaqua-bis-(5-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ato-?N,O)zinc trihydrate.

ABSTRACT: 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. The carb-oxy group links with the carboxyl-ate group of the same ligand via an intra-molecular O-H?O hydrogen bond. 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 compound, [Co(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·3H(2)O, the Co(II) cation, located on an inversion center, is N,O-chelated by two 5-carboxy-2-ethyl-1H-imidazole-4-carboxylate anions and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. Only one carboxy group of the anion is deprotonated, and the two carboxyl groups of the same anion are linked via an intra-molecular O-H?O hydrogen bond. One of the lattice water mol-ecules is located on an inversion center, its H atom equally disordered over two positions. One of H atoms of another lattice water mol-ecules is also equally disordered over two sites. Water H atoms and the amino H atom all are involved in an inter-molecular hydrogen-bonded network in the crystal.

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.

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.
