Abstract

A novel organically templated cobalt-vanadium oxalate, (C(2)H(10)N(2))[Co(2)(C(2)O(4))V(4)O(12)], was synthesized under mild hydrothermal conditions and characterized by single-crystal/powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. The compound crystallizes in an orthorhombic system with space group Cmcm and cell parameters a = 11.527(2) A, b = 9.9476(18) A, c = 14.780(3) A. The compound possesses 3-dimensional topologies with sodalite analogue structure and is constructed by C(2)O(4)-incorporated beta cage units. On the basis of the results of TG/DTA analyses, the structure is thermally stable up to approximately 573 K.
