Penta-aqua-(1H-benzimidazole-5,6-dicarboxyl-ato-?N)nickel(II) penta-hydrate.

ABSTRACT: 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.

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.

Penta-aqua-(1H-benzimidazole-5,6-di-carboxyl-ato-?N)cobalt(II) penta-hydrate.

Project description:In the title mononuclear complex, [Co(C(9)H(4)N(2)O(4))(H(2)O)(5)]·5H(2)O, the Co(II) atom exhibits a distorted octa-hedral geometry involving an N atom of a 1H-benzimidazole-5,6-dicarboxyl-ate ligand and five water O atoms. A supra-molecular network is generated through inter-molecular O-H?O hydrogen-bonding inter-actions involving the coordinated and uncoordinated water mol-ecules and the carboxyl O atoms of the organic ligand. An inter-molecular N-H?O hydrogen bond is also observed.

The Cu(II) atom is six-coordinated by one N atom from the bdc ligand and five O atoms from water mol-ecules, giving an octa-hedral coordination geometry. Hydrogen bonds link the mononuclear complex and uncoordinated water mol-ecules into a three-dimensional network.

Project description:In the title complex, [Mn(C(9)H(4)N(2)O(4))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination completed by one N atom from one 1H-benzimidazole-5,6-dicarboxyl-ate ligand, two O atoms from two different 1H-benzimidazole-5,6-dicarboxyl-ate ligands, and three O atoms from three water mol-ecules. Two bridging water mol-ecules and two bridging carboxyl-ate groups from a 1H-benzimidazole-5,6-dicarboxyl-ate ligand connect two Mn(II) ions into a dimeric structure. In the crystal, extensive inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonding forms a three-dimensional network.

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

Project description: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.

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.

Aqua-(1H-benzimidazole-?N)(pyridine-2,6-dicarboxyl-ato-?O,N,O)copper(II) 0.75-hydrate.

Project description:The title complex, [Cu(C(7)H(3)NO(4))(C(7)H(6)N(2))(H(2)O)]·0.75H(2)O, consists of discrete monomeric units. The Cu(II) atom is coordinated by two carboxyl-ate O atoms and the N atom from a dipicolinate unit and by an N atom from a benzimidazole ligand. The distorted square-pyramidal geometry is completed by a longer axial bond to the O atom of a water mol-ecule. The mol-ecular structure and packing are stabilized by classical O-H?O and N-H?O hydrogen bonds, also including a disordered crystal water molecule.

Project description:In the title complex, [Ni(C(9)H(4)N(2)O(4))(C(12)H(8)N(2))(H(2)O)(2)](n), the Ni(II) atom is hexa-coordinated by one N and one O atom from two different 1H-benzimidazole-5,6-dicarboxyl-ate ligands, two N atoms from one 1,10-phenanthroline ligand and two water mol-ecules. The flexible 1H-benzimidazole-5,6-dicarboxyl-ate ligands link the Ni(II) centres, forming an infinite zigzag chain parallel to [001]. 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.

The Ni(II) ions are in slightly distorted coordination environments. In the crystal structure, inter-molecular O-H?O and weak C-H?O hydrogen bonds link cations and water mol-ecules into a three-dimensional network.

Hexaaqua-nickel(II) tetra-aqua-bis-(?-pyridine-2,6-dicarboxyl-ato)bis-(pyridine-2,6-dicarboxyl-ato)trinickelate(II) octa-hydrate.

Project description:The title compound, [Ni(H(2)O)(6)][Ni(3)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·8H(2)O, was obtained by the reaction of nickel(II) nitrate hexa-hydrate with pyridine-2,6-dicarb-oxy-lic acid (pydcH(2)) and 1,10-phenanothroline (phen) in an aqueous solution. The latter ligand is not involved in formation of the title complex. There are three different Ni(II) atoms in the asymmetric unit, two of which are located on inversion centers, and thus the [Ni(H(2)O)(6)](2+) cation and the trinuclear {[Ni(pydc)(2)](2)-?-Ni(H(2)O)(4)}(2-) anion are centrosymmetric. All Ni(II) atoms exhibit an octa-hedral coordination geometry. Various inter-actions, including numerous O-H?O and C-H?O hydrogen bonds and C-O?? stacking of the pyridine and carboxyl-ate groups [3.570?(1), 3.758?(1) and 3.609?(1)?Å], are observed in the crystal structure.
