Hydrothermal Synthesis and Crystal Structure of Polyoxovanadate Linked by Transition Metal Complex Fragments [Co(o-phen)]V2O6·H2O

Abstract

Abstract: The hydrothermal reaction of NH₄VO₃, CoCl₂·6H₂O, o-phen and H₂O gave a novel two-dimensional layered polyoxovanadate, [Co(o-phen)]V₂O₆·H₂O, which was constructed from {V₂O₆} chains linked by Co(o-phen) complex fragments. [Co(o-phen)]V₂O₆·H₂O was characterized by IR, TG and single-crystal X-ray diffraction. It crystallizes in monoclinic space group P2(1)/c with a= 0.785 2(9)_nm, b=2.118 3(2)_nm, c=0.946 3(11)_nm, β=112.827(2)°, V=0.145 1(3)_nm³, D_c=2.074 g/cm³, Z=4, R₁=0.038 8, wR₂=0.094 1.
