Syntheses and Structure of α-(+)-Co(en)3V3O6·H2O

Abstract

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, D_c=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.
