Poly[(μ(3)-biphenyl-3,3'-dicarboxyl-ato)(1,10-phenanthroline)cadmium].

ABSTRACT: In the title compound, [Cd(C(14)H(8)O(4))(C(12)H(8)N(2))](n), the Cd(II) ion is seven-coordinated in a distorted penta-gonal-bipyramidal coordination geometry by five O atoms from bridging biphenyl-3,3'-dicarboylate (dpda) ligands and two N atoms from a 1,10-phenanthroline (1,10-phen) ligand. In the crystal, dinuclear units with a Cd⋯Cd separation of 3.8208 (7) Å are observed. Each of these dinuclear units is bridged via 3,3'-bpda in a chelating/chelating and bridging fashion, generating a zigzag chain along the c axis. Neighboring chains are further packed via weak π-π inter-actions between inter-chain parallel 1,10-phen rings [centroid-centroid distance = 3.5197 (9) Å] into a three-dimensional supra-molecular architecture.

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:In the title compound, {[Co(2)(C(16)H(6)O(8))(C(12)H(8)N(2))(H(2)O)(2)]·H(2)O}(n), one Co(II) ion has a {CoN(2)O(4)} distorted octa-hedral environment defined by two N atoms of one 1,10-phenanthroline (phen) ligand, three O atoms of the carboxyl-ate groups of three biphenyl-3,3',4,4'-tetra-carboxyl-ate (BPTC) ligands, one of which is bidentate, and one O atom from one coordinated water mol-ecule. The other Co(II) atom is surrounded by six O atoms from four different BPTC ligands and one coordinated water mol-ecule. Each BPTC ligand forms eight coordination bonds with seven Co(II) atoms, leading to a layer structure along the ac plane. Uncoordinated water mol-ecules occupy the space between the layers, and inter-act via inter-layer O-H?O hydrogen bonds along the b axis, generating a three-dimensional supra-molecular network.

Project description:In the title coordination polymer, {[Mn(C(12)H(14)O(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), the Mn(II) atom has a highly distorted cis-MnN(2)O(4) octa-hedral geometry arising from its coordination by a bidentate phenanthroline ligand, a water mol-ecule and monodentate and bidentate adamantane-1,3-dicarboxyl-ate dianions.
