摘　　要：The paramagnetic cis dioxo molybdenum(V) complex, [NH 2~CH 2~CH 2~NH 3] 3[Mo VO 2(HNC 6H 4O) 2] was obtained by the reaction of tetra butyl ammonium β octamolybdate with o aminophenol and ethylenediamine in the mixed solvent of CH 3OH and CH 3CN, and characterized by IR, NMR, EPR spectroscopy and X ray diffraction analysis. The determination of single crystal X ray analysis revealed that the central Mo V ion metal center exhibits distorted octahedral coordination with cis dioxo o aminophenol. The EPR spectra of both the complex and flavoenzyme show similarly. Thus it suggests that the complex anion [Mo VO 2(HNC 6H 4O) 2] 3- and flavoenzyme have related structure feature.The paramagnetic cis dioxo molybdenum(V) complex, [NH 2~CH 2~CH 2~NH 3] 3[Mo VO 2(HNC 6H 4O) 2] was obtained by the reaction of tetra butyl ammonium β octamolybdate with o aminophenol and ethylenediamine in the mixed solvent of CH 3OH and CH 3CN, and characterized by IR, NMR, EPR spectroscopy and X ray diffraction analysis.
