A copper complex[Cu2(C2O4)(2,2’-bpy)2(NO3-)2(H2O)2]was prepared based on α-ketoglutaric acid,2,2’-bipyri-dine with copper acetate under hydrothermal condition. And the complex was characterized by Single-crystal X-Ray diffraction,IR spectroscopy,powder X-Ray diffraction and TGA. Single crystal X-Ray diffraction analysis reveals that the title complex crystallizes in monoclinic symmetry with P21/n space group,and the ligands are oxalate and 2,2’-bipyridine. The complex moleculars connect-ed each other by the hydrogen bonding and π…π stacking interactions to give a three dimensional supramolecular structure. The complex was applied to the epoxidation of styrene reaction,and the catalytic results show that the complex catalyst possesses 47. 2%styrene conversation-and 43. 6%selectivity of epoxyethylbenzene at 80 ° C for 6 h. Moreover,the complex catalyst can be recycled two times without any loss of catalytic activity.
