Co(en) 3V 3O 6·H 2O has been synthesized by using hydrothermal method and characterized by IR, ICP, XPS and X ray diffraction analysis. The results of the X ray diffraction analysis show that structure of Co(en) 3(VO 3) 3·H 2O is orthorhombic with P2(1)2(1)2(1) , and the crystal data are a =0 819 2(7) nm, b =1.263 9(1) nm, c =1.804 8(2) nm, V =1.868 8(3) nm 3, Z=4, D c=1.973 g/cm 3, F (000)=1 124, R 1=0.040 7, wR 2=0.094 9, ( Δ/ρ ) max =706 e/nm 3 and ( Δ/ρ ) min =-452 e/nm 3. The results of XPS show that the Co 2+ was oxidized to Co 3+ (en) 3 at about pH=7.0 in the aqueous solution.
