摘　　要：合成了Tb（Ⅲ）、Y（Ⅲ）、Nd（Ⅲ）硝酸盐与N，N-二亚水杨基乙二胺、二甲基亚观的配合物［RE（C6H4OHCHNC6H4NCHC6H4OH）（NO3）3（CH3SOCH3）］．Tb（Ⅲ）配合物晶体为单斜晶系，空间群P21／n，a=0．9628（3）nm，b=1．6439（4）nm，C=1．6256（2）nm，β=102．78（2）°,V＝2．509（2）nm3，Dx＝1．830g／cm3，Z＝4，μ＝2．996mm-1，F（000）＝1368，R＝0．043，Rw=0.046．Tb（Ⅲ）的配位数是9，配位几何为单帽四方反核柱．所有的配位原子都是氧原子．两个中心离子被双Schiff碱桥联，形成一维无限长链．The complexes of Tb (Ⅲ ), Y (Ⅲ ), Nd (Ⅲ ) nitrate with N, N-disalicylideneethylenediamine, dimethyl sulfoxide as the ligands were synthesized. Their molecularcomposition are [RE(C6H5OHCHNC2H4NCHC2H4OH) (NO3)3 (CH3SOCH3)]. The molecularstructures of the complexes were determined by X-ray diffraction. The crystal of Tb (Ⅲ )complex is monoclinic with space group P 21/n, a = 0' 962 8 (3) nm, b= 1' 643 9 (4) nm,c=1. 625 6(2) nm, β=102. 78(2)°, V=2. 509(2)nm3, Dx=1.830 g/cm3, Z=4, p=2. 996mm-1, F (000) = 1 638, R = 0. 043, Rw= 0. 046. The coordination number of Tb (Ⅲ ) is 9with the geometry of a monocapped square antiprism. All of coordination atoms are oxygenatoms. The two central ions were bridged by the two Schiff base, resulting in an infinitechain.
