Catena-Poly[[[2-(2-pyrid-yl)-1H-benz-imidazole]cadmium(II)]-?-benzene-1,4-dicarboxyl-ato].

ABSTRACT: In the title compound, [Cd(C(8)H(4)O(4))(C(12)H(9)N(3))](n), each Cd(II) ion is six-coordinated in a distorted octa-hedral geometry by four carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate anions (L), and two N atoms from one 2-(2-pyrid-yl)benzimidazole ligand. The neighboring Cd(II) ions are bridged by the L ligands, forming a zigzag polymeric chain structure. The chains are further extended into a three-dimensional supra-molecular structure through inter-molecular N-H?O hydrogen bonds.

Project description:In the title compound, [Cu(C(8)H(4)O(4))(C(3)H(4)N(2))(2)](n), the Cu(II) atom is four-coordinated by two carboxyl-ate O atoms from two different terephthalate ligands and two N atoms from two imidazole ligands in a slightly distorted square-planar coordination environment. Each terephthalate ligand acts as a bis-monodentate ligand that binds two Cu(II) atoms, thus forming two unique chains extending parallel to [110]. The imidazole ligands are attached on both sides of the chains.

catena-Poly[[[aqua-(1,10-phenan-throline)cadmium(II)]-?-benzene-1,4-dicarboxyl-ato] benzene-1,4-dicarboxylic acid hemisolvate].

Project description:A new cadmium(II) coordination polymer, {[Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5C(8)H(6)O(4)}(n), has been synthesized under hydro-thermal conditions. The asymmetric unit contains one Cd(II) atom, one benzene-1,4-dicarboxyl-ate anion, one 1,10-phenanthroline ligand, one coordinated water mol-ecule and half of an uncoordinated benzene-1,4-dicaboxylic acid solvent mol-ecule. The Cd(II) atom is in the centre of a monocapped distorted octa-hedron made up of four O atoms of two chelating benzene-1,4-dicarboxyl-ate anions, one water O atom and two 1,10-phenanthroline N atoms. The metal centres are connected via bis-chelating benzene-1,4-dicarboxyl-ate anions into a zigzag chain structure along [001]. These chains are further connected by O-H?O hydrogen bonds between the water mol-ecules and adjacent carboxyl-ate O atoms. Additional O-H?O hydrogen bonding between the uncoordinated benzene-1,4-dicaboxylic acid mol-ecules along [010] consolidates the structure.

Project description:In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help to stabilize the crystal structure.

Project description:In the title compound, {[Cu(C(12)H(6)O(4))(C(3)H(4)N(2))(2)(H(2)O)]·2H(2)O}(n), the Cu(II) cation is coordinated by two naphthalene-1,4-dicarboxyl-ate (naph) dianions, two imidazole mol-ecules and one water mol-ecule in a distorted square-pyramidal geometry. The Cu-O bond distance in the apical direction is 0.509?(3)?Å longer than the mean Cu-O bond distance in the basal plane. The naph dianion bridges two Cu(II) cations, forming a one-dimensional polymeric chain. The coordinated water mol-ecule is hydrogen-bonded to the carboxylate groups and imidazole ligands of adjacent polymeric chains, forming a three-dimensional supra-molecular structure. No ?-? stacking is observed in the crystal structure. One solvent water molecule is disordered equally over two positions.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

Project description:The title compound, [Cd(C(8)H(8)O(5))(C(3)H(4)N(2))(2)](n), was synthesized by the reaction of 7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxylic anhydride, cadmium acetate and imidazole. The Cd(II) atom is seven-coordinated in a distorted penta-gonal-bipyramidal configuration by five O atoms from carboxyl-ate groups of three 7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxylate ligands and two N atoms from two imidazole ligands. The crystal structure is stabilized by N-H?O and C-H?O hydrogen-bonding and C-H?? inter-actions.

Project description:In the title compound, {[Cd(C(8)H(4)O(4))(C(11)H(6)N(2)O)(H(2)O)(3)]·2H(2)O}(n), the Cd(II) atom is seven-coordinated by two N atoms from the phenanthroline-derived 4,5-diaza-fluorene-9-one ligand, two O atoms from one bidentate benzene-1,3-dicarboxyl-ate ligand and three O atoms from the three water mol-ecules in a distorted penta-gonal-bipyramidal arrangement. Moreover, there are two dissociative water mol-ecules in each unit. Neighbouring units inter-act through π-π inter-actions [centroid-centroid distances = 3.325 (3) and 3.358 (4) Å] and O-H⋯O hydrogen-bonding, resulting in a two-dimensional network extending parallel to (001).
