苯甲酸根为桥的双核Eu(Ⅲ)配合物的合成及晶体结构

Synthesis, Characterization and Structure of Tetrabenzoyloxy Bridged Binuclear Eu(Ⅲ) Complex

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．

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. 081 56(7) nm, b = 1. 193 31(7) nm, c =1. 244 01(8) nm, a=104. 972(5)o, g=93. 661 (5)o, y=113. 297(5)o, V=1- 399 4(2) nm3,Z= 1, R= 0. 043 7, R.=0. 041 4. UV-Vis and IR spectra of the complex were determinedand discussed.
