摘　　要：利用水热技术,以钒酸盐、二价过渡金属化合物及含N的螯合配体为起始反应物,合成了异核簇化合物{[Cd(2,2’—bipy)2]2V4O12}.H2O.分子式为:C40H34Cd2N8O13V4.晶胞参数为:orthorhombic,Ibca,a=16.0479,b=17.0273,c=33.5371,Z=2.化合物的结构可描述为[V4O12]4-环以共价作用同两个[Cd(2,2’—bipy)2]2+相连,[V4O12]4-环为椅式构象.A novel inorganic-organic hybrid compound { [ Cd （ 2,2＇ -bipy ） 2 ] 2V4O12 }·H2O was synthesized under hydrothermal condition and it＇s structure was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectrum.The title compound crystallize is a orthorhombic Ibca crystal system, crystal parameters a = 16.047 9, b = 17.027 3,c = 33.537 1,Z = 2.The compound has crystallographic two fold rotation symmetry.A {V4O12} ring links through oxo groups of pairs of adjacent vanadium sites to two Cd（bipy）2^2＋ moieties. The molecules are assembled into layers parallel to the ab plane by aromatic π-π stacking interactions involoving the bipy ligands.
