Hydrothermal synthesis and crystal structure of a new molybdenum oxide compound with manganese-o-phen subunit: [Mn(o-phen)(H2O)MoO4]center dot H2O (o-phen = o-phenanthroline)

摘要

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 Na2MoO4.2H(2)O, 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) Angstrom, b = 10.4498(2) Angstrom, c = 10.5720(2) Angstrom, alpha = 73.26(7)degrees, beta = 83.34(8)degrees, gamma = 77.33(9)degrees, V = 725.5089(0) Angstrom(3), Z = 2, and R-1 = 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 pi-pi stacking interactions to a 3D supermolecular structure. (C) 2004 Elsevier Inc.
