Diaqua-bis(5-carb-oxy-2-methyl-1H-imidazole-4-carboxyl-ato-?N,O)cobalt(II) dimethyl-formamide disolvate.

ABSTRACT: 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.

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.

Diaqua-bis-(pyridine-2-carboxyl-ato-κN,O)manganese(II) dimethyl-formamide hemisolvate.

Project description:There are two crystallographically independent complex mol-ecules with very similar geometries in the unit cell of the title compound, [Mn(C(6)H(4)NO(2))(2)(H(2)O)(2)]·0.5C(3)H(7)NO. The central ion is situated in a distorted octa-hedral environment of two N- and four O-donor atoms from two pyridine-2-carboxyl-ate ligands and two cis-disposed water mol-ecules. The carboxyl-ate ligands are coordinated in a chelate fashion with the formation of two five-membered rings. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, thus forming hydrogen-bonded walls disposed perpendicularly to the bc plane.
