Two inorganic-organic hybrid compounds with the formula M(4,4'-bipy)(H2O)V2Se2O10 (M = Co, Ni) werehydrothermally synthesized and characterized by single-crystal X-ray diffraction. Compounds Co(4,4'-bipy)(H2O)V2Se2O10 (1) and Ni(4,4'-bipy)(H2O)V2Se2O10 (2), which are structural analogues, crystallize in the triclinic spacegroup P

[M(4,4'-bipy)(H2O)V2Se2O10] (M = Co, Ni) have a three-dimensional structure and consist of two subunits, [(VO2)(SeO3)]-infinite chains and [M(4,4'-bipy)(H2O)]2+ fragments. The [(VO2)(SeO3)]- chains are composed of [V2Se4O14]4- clusterslinked by VO4N triangular bipyramids. The 4,4'-bipy molecule as a bifunctional organic ligand is directly linked toCo or Ni and V atoms, affording the three-dimensionality. The compounds were characterized by infrared spectroscopyand differential thermal and thermogravimetric analyses.
