摘要： 在EtOH：H2O=2:1的溶剂中,以Eu(NO3)3·6H2O、C6H5COONa和Phen(邻菲哈啉)为原料,合成了四桥双核配合物[Eu2(Phen)2(C6H5COO)6]．晶体属三斜晶系,空间群P1,a=1．08156(7)nm,b=1．19331(7)nm,c=1.24401(8)nm,a=104.972(5)°,β=93．661(5)°γ=113.297(5)°,Z=1．R=0.0437．晶体中2个Eu原子处于晶体学等效位置,配位数为9,Eu-Eu间距离为0．4052nm．讨论了标题化合物的UV－Vis谱与其它Eu3+离子谱的异同．

关键词: Eu(Ⅲ)配合物, 晶体结构, UV－Vis光谱, IR谱

Abstract: The crystal of complex [Eu2(phen)2(C6H5COO)6] was synthesized and its struc-ture of the single crystal was determined by X-ray diffraction.The crystal belongs to a tri-clinlc system, space group P1, with a=1.08156(7) nm, b=1.19331(7) nm, c=1.24401(8) nm, a=104.972(5)o, g=93.661 (5)o, y=113.297(5), V=1.3994(2) nm3,Z=1, R=0.0437, Rw=0.0414.UV-Vis and IR spectra of the complex were determinedand discussed.

Key words: Eu(Ⅲ) complex, Crystal structure, UV-Vis spectrum, IR spectrum
