Poly[[tetraaqua-bis(?(3)-1H-benzimidazole-5,6-dicarboxyl-ato)dicobalt(II)] trihydrate].

ABSTRACT: The title complex, {[Co(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·3H(2)O}(n), was synthesized hydro-thermally. The unique Co(II) ion is coordin-ated in a distorted octa-hedral coordination environment by two water mol-ecules and three symmetry-related 1H-benzimid-azole-5,6-dicarboxyl-ate (Hbidc) ligands. The Hbidc ligands coordinate via a bis-chelating and mono-chelating carboxyl-ate group and by an imidazole group N atom, bridging the Co(II) ions and forming an extended two-dimensional structure in the ab plane. In the crystal structure, inter-molecular N-H?O and O-H?O hydrogen bonds connect complex and solvent water mol-ecules, forming a three-dimensional supermolecular network. One of the solvent water mol-ecules lies on a twofold rotation axis.

Project description:The polymeric title compound, {[Ba(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)]·4.5H(2)O}(n), adopts a layer structure parallel to (001) in which adjacent Ba(II) atoms are connected by two benzimidazole-5,6-dicarboxyl-ate dianions, one functioning in a μ(4)-bridging mode and the other in a μ(5)-bridging mode. The Ba atom having water in its coordination environment as well as the Ba atom without water exist in a nine-coordinate polyhedron of O atoms; the geometry is difficult to derive. Lattice water mol-ecules occupy the space between layers and inter-act with the layers through O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds. ne of the five lattice water molecules is equally disordered around an inversion centre and shows half-occupancy.
