A new oxalato- and acetato-bridged Mn(II) polymer, [Mn2(C12N2H8)2( μ-C2O4)( μ-CH3COO)2] n ·4 nH2O was synthesized and characterized by X-ray diffraction analysis. The compound exhibits a one-dimensional chain-like structure, in which the Mn atom is coordinated by two nitrogen atoms and four carboxyl oxygen atoms with octahedral coordination geometry. As far as we are aware, this type of coordination polymer involving the simultaneously bridging oxalate and acetate ligands has not been studied so far. [ABSTRACT FROM AUTHOR]

A new one-dimensional molybdenum oxide compound with manganese-o-phen subunit: [Mn(o-phen)(H2O)MoO4]·H2O (1) (o-phen=o-phenanthroline) was synthesized by thehydrothermal reaction of Na2MoO4·2H2O, MnSO4·H2O, oxalic acid, o-phenanthroline (o-phen) and water. Its structure was determined by elemental analyses, ESR spectrum, TG analysis, IR spectrum and single-crystal X-ray diffraction. Compound 1 crystallizes in triclinic system, space group P-1 with a=7.0401(2) Å, b=10.4498(2) Å, c=10.5720(2) Å, α=73.26(7)°, β=83.34(8)°, γ=77.33(9)°, V=725.5089(0) Å3, Z=2, and R1=0.0322 for 2337 observed reflections. Compound 1 exhibits one-dimensional chain structure. The chains are linked up via hydrogen bonding to 2D layers, which are further assembled through π–π stacking interactions to a 3D supermolecular structure. [Copyright &y& Elsevier]
