Poly[aqua-bis(?(4)-naphthalene-1,4-di-carboxyl-ato)(1,10-phenanthroline-5,6-dione)dimanganese(II)].

ABSTRACT: The three-dimensional coordination polymer, [Mn(2)(C(12)H(6)O(4))(2)(C(12)H(6)N(2)O(2))(H(2)O)](n), features a water-coord-inated Mn(II) ion and an N-heterocycle-chelated Mn(II) ion, both in six-coordinate octa-hedral geometries. Of the two rigid dianions, one is bonded to four Mn(II) ions, with each of the O atoms being connected to a different metal ion. The other dianion uses one carboxyl-ate group to chelate to one Mn(II) ion and its other carboxyl-ate group to bind to two Mn(II) ions.

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 polymeric compound, [Mn(2)(C(10)H(2)O(8))(C(12)H(8)N(2))(2)](n), was obtained by the reaction of manganese(II) chloride tetra-hydrate with benzene-1,2,4,5-tetra-carboxylic acid (H(4)bta) in aqueous solution. Each Mn(2+) ion is coordinated in a distorted octa-hedral geometry by two N atoms from one 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.116?(2)-2.237?(2)?Å] from three bta(4-) ligands, which also act as bridging groups between the Mn(2+) ions.
