Bis(4-carb-oxy-pyridine-2-carboxyl-ato-?N,O)copper(II) dimethyl sulfoxide disolvate.

ABSTRACT: In the title complex, [Cu(C(7)H(4)NO(4))(2)]·2C(2)H(6)OS, the Cu(II) atom is situated on an inversion centre and is N,O-chelated by two monoanionic 4-carb-oxy-pyridine-2-carboxyl-ate ligands in a slightly distorted square-planar coordination geometry. The dimethyl sulfoxide solvent mol-ecules and Cu(II) complex mol-ecules are linked by O-H?O hydrogen bonding. In addition, C-H?O contacts and ?-? inter-actions [centroid-centroid distance = 3.590?(1)?Å] occur.

Project description:In the title compound, [Co(C(6)H(5)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Co(II) ion lies on an inversion center and adopts a slightly distorted CoN(2)O(4) octa-hedral geometry binding two bidentate chelating 5-carb-oxy-2-methyl-1H-imidazole-4-carboxyl-ate (H(2)MIDA(-)) monoanionic ligands and two axial aqua ligands. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link neighboring mol-ecules, generating a two-dimensional framework containing eight-membered H(4)O(4) rings. In addition, the dimethyl-formamide solvent mol-ecules are hydrogen bonded to the two-dimensional framework via the NH groups of the H(2)MIDA(-) ligands.

Diaqua-bis-(4-carb-oxy-2-propyl-1H-imidazole-5-carboxyl-ato-κN,O)zinc(II) N,N-dimethyl-formamide disolvate.

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. The asymmetric unit consists of one Zn(II) atom located on a center of inversion as well as one anion, one water mol-ecule and one additional dimethyl-formamide mol-ecule that occupy general positions. Between the carboxyl and the carboxyl-ate group an intra-molecular hydrogen bond is found in which the hydroxy H atom is disordered. Disorder is also found for the H atoms of one of the three methyl groups. In the crystal structure, additional inter-molecular N-H⋯O and O-H⋯O hydrogen bonding is found.

The axial positions are occupied by two O atoms from two water mol-ecules. A two-dimensional supra-molecular network parallel to (001) is constructed by N-H?O and O-H?O hydrogen bonds. An intra-molecular O-H?O hydrogen bond is also observed.
