Trans-Diaqua-bis-[5-carb-oxy-4-carboxyl-ato-2-(4-pyridinio)-1H-imidazol-1-ido-κN,O]zinc(II).

ABSTRACT: In the title complex, [Zn(C(10)H(6)N(3)O(4))(2)(H(2)O)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two trans-positioned N,O-bidentate and zwitterionic 5-carb-oxy-4-carboxyl-ato-2-(4-pyridinio)-1H-imidazol-1-ide (H(2)PIDC(-)) ligands and two water mol-ecules, defining a distorted octa-hedral environment. The complete solid-state structure can be described as a three-dimensional supra-molecular framework, stabilized by extensive hydrogen-bonding inter-actions involving the coordinated water mol-ecules, uncoordin-ated imidazole N atom, protonated pyridine N and carboxyl-ate O atoms of the H(2)PIDC(-) ligands.

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. 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: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.
