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

ABSTRACT: 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.

Aqua-(4-hydroxy-pyridine-2,6-dicarboxyl-ato)(1,10-phenanothroline)copper(II) 4.5-hydrate.

Project description:The title compound, [Cu(C(7)H(3)NO(5))(C(12)H(8)N(2))(H(2)O)]·4.5H(2)O or [Cu(hypydc)(phen)(H(2)O)]·4.5H(2)O (phen is 1,10-phenanthroline and hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid), was obtained by the reaction of copper(II) nitrate hexa-hydrate with the proton-transfer compound (phenH)(2)(hypydc) in aqueous solution. Both the cationic and the anionic fragments of the proton-transfer compound are involved in complexation. Each Cu(II) atom has a distorted octa-hedral geometry. It is hexa-coordinated by three O atoms and three N atoms, from one phen fragment (as bidentate ligand), one (hypydc)(2-) unit (as tridentate ligand) and a water mol-ecule. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds, and π-π stacking inter-actions [centroid-to-centroid distance 3.5642 (11) Å] between the phen ring systems, contribute to the formation of a three-dimensional supra-molecular structure.

Poly[[aqua-(μ(5)-1H-benzimidazole-5,6-dicarboxyl-ato)(μ(4)-1H-benzimidazole-5,6-dicarboxyl-ato)dibarium] 4.5-hydrate].

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.

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.

Project description:In the title compound, {[Ca(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(12)]·10.5H(2)O}(n), the Eu(III) ion is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate (PDA) ligands, forming a [Eu(PDA)(3)](3-) building block. The Ca(2+) ions adopt two types of coordination geometries. One Ca(2+) ion, lying on a twofold rotation axis, is eight-coordinated by four carboxyl-ate O atoms from four PDA ligands and four water mol-ecules, and the other two Ca(2+) ions, each lying on an inversion center, are six-coordinated by two carboxyl-ate O atoms from two PDA ligands and four water mol-ecules. The carboxyl-ate groups bridge the Eu(III) and Ca(2+) ions into a three-dimensional porous framework, with channels extending along [010] and [001] in which lattice water mol-ecules are located. Two of the lattice water mol-ecules are disordered over two sets of sites with equal occupancy and one water mol-ecule is 0.25-occupied. Numerous O-H?O hydrogen bonds involving the water mol-ecules and carboxyl-ate O atoms are present.

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

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.

Project description:The title compound, [Cu(3)(C(7)H(3)NO(4))(4)(C(2)H(8)N(2))(2)]·C(2)H(8)N(2)·4H(2)O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarb-oxy-lic acid (H(2)dipic) and ethyl-enediamine (en) in an aqueous solution. All of the Cu(II) atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octa-hedral geometry with N(2)O(4) and N(4)O(2) environments for the outer and central Cu(II) atoms, respectively.
