Poly[(?-1H-benzimidazole-5,6-dicarboxyl-ato)lead(II)].

ABSTRACT: The crystal structure of the two-dimensional polymeric title compound, [Pb(C(9)H(4)N(2)O(4))](n), comprises one crystallo-graphic-ally independent Pb(II) atom and one fully deprotonated 1H-benzimidazole-5,6-dicarboxyl-ate (H(2)L) ligand. The Pb(II) atom is seven-coordinated by six O atoms and one N atom from the H(2)L ligands, giving a capped octa-hedral coordination geometry. The structure is a layered two-dimensional coordination polymer extending parallel to (100) with N-H?O hydrogen bonds inter-actions between the layers, stabilizing the crystal structure.

Project description:The three-dimensional polymeric title compound, {[Zn(C(9)H(4)N(2)O(4))]·H(2)O}(n), contains one crystallographically independent Zn(II) atom, one fully deprotonated 1H-benzimid-azole-5,6-dicarboxyl-ate (bdc) ligand and one uncoordinated water mol-ecule. The Zn(II) atom is four-coordinated by three O atoms and one N atom from the bdc ligands, giving a distorted tetra-hedral coordination geometry. The uncoordinated water mol-ecule is bound to the main structure through a strong bdc-water N-H?O hydrogen bond, and two much weaker water-bdc O-H?O inter-actions.

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.

In the crystal, extensive inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonding forms a three-dimensional network.

The crystal packing is governed by inter-molecular hydrogen-bonding inter-actions of the O-H?O, N-H?O and C-H?O types.

Project description: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:Each of the carboxyl-ate -CO(2) fragments of the dianion ligand in the title compound, {[Sr(C(9)H(4)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), chelates to a Sr(II) atom and at the same time, one of the two O atoms coordinates to a third Sr(II) atom. The ?(4)-bridging mode of the dianion generates a square-grid layer motif; adjacent layers are connected by O-H?O, O-H?N and N-H?O hydrogen bonds, forming a three-dimensional network. The eight-coordinate Sr atom exists in a distorted square-anti-prismatic geometry. The crystal studied was a non-merohedral twin with a minor twin component of 24%.

Project description:In the title compound, {[Co(C9H4N2O4)(C12H8N2)(H2O)2]·1.5H2O} n , the Co(II) atom is hexa-coordinated by one N atom and one O atom from two symmetry-related 1H-benzimidazole-5,6-dicarboxyl-ate ligands, two N atoms from one 1,10-phenanthroline ligand (phen) and two water mol-ecules. The dihedral angle between the 1H-benzimidazole-5,6-dicarboxyl-ate and 1,10-phenanthroline ligands is 74.41?(4)°. The crystal packing is governed by inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions. All water (coordin-ating and lattice) mol-ecules take part in the hydrogen-bonding inter-actions. In addition, there are ?-? stacking inter-actions between inversion-related phen ligands, the shortest centroid-centroid distance being 3.7536?(16)?Å. One of the two lattice water molecules shows half-occupancy.

Project description:In the title mononuclear complex, [Ni(C(9)H(4)N(2)O(4))(H(2)O)(5)]·5H(2)O, the Ni(II) atom is six-coordinated by one N atom from a 1H-benzimidazole-5,6-dicarboxyl-ate ligand and by five O atoms from five water mol-ecules and displays a distorted octa-hedral geometry. Inter-molecular O-H?O hydrogen-bonding inter-actions among the coordinated water mol-ecules, solvent water mol-ecules and carboxyl O atoms of the organic ligand and additional N-H?O hydrogen bonding lead to the formation of a three-dimensional supra-molecular network.
