Abstract: Co(en)3V3O6·H2Ohas been synthesized by using hydrothermal method and characterized by IR, ICP, XPSand X-ray diffraction analysis. The results of the X-ray diffraction analysis show that structure of Co(en)3(VO3)3·H2Ois orthorhombic with P2(1)2(1)2(1), and the crystal data are a=08192(7) nm, b=1.2639(1) nm, c=1.8048(2) nm, V =1.8688(3) nm3, Z=4, Dc=1.973 g/cm3, F (000)=1124, R 1=0.0407, wR2=0.0949, ( Δ/ρ )max=706 e/nm3and ( Δ/ρ )min =-452 e/nm3. The results of XPSshow that the Co 2+was oxidized to Co 3+(en)3at about pH=7.0 in the aqueous solution.
