摘要：

Cis-dioxo-tungsten(VI) complex, (NH2CH2CH2NH2)[(NH2CH2CH2NH3)(2)(WO2)-O-VI(NHC6H4NH)(2)](2)(H2O)-H-. is synthesized at room temperature by the reaction of sodium tungstate with o-phenylenediamine. The crystal structure of complex was determined by X-ray diffraction structural analysis. The results show that complex belongs to monoclinic system with space group P2(1)/c, a=0.712 8(2) nm, b=3.0811(10) nm, c=0.981 9(3) nm, beta=102.615(4)degrees, V= 2.1044(11) nm(3), Z=2, mu=55.26 cm(-1), F(000)=1176. Compared the complex with its analogous biomimetic complexes of the cofactor of molybdoenzymes and tungstoenzymses, it is found that the variance of the coordination atoms and the metal ions center have no influence on the coordination feature, and exhibits distored octahedral coordination with cis-dioxo o-phenylenediamine.
