摘　　要：合成了硝酸钇（Ⅲ）与双希夫碱Ｎ，Ｎ′－二亚水杨基乙二胺、二甲基亚砜的配合物〔Ｙ（Ｃ６Ｈ４ＯＨＣＨＮＣ２Ｈ４ＮＣＨＣ６Ｈ４ＯＨ）（ＮＯ３）３（ＣＨ３ＳＯＣＨ３）〕。ｘ—射线单晶结构分析表明该晶体属单斜晶系、空间群为Ｐ２１／ｎ，ａ＝０．９６３１（２）ｎｍ，ｂ＝１．６４１４（５）ｎｍ，ｃ＝１．６２０９（３）ｎｍ，β＝１０２．９８（２）°，Ｚ＝４，Ｄｘ＝１．６５３Ｍｇ·ｍ－３。Ｙ（Ⅲ）配位数为９，配位几何为畸变的单帽四方反棱柱，所有的配位原子均为氧原子，分别来自三个硝酸根，一个二甲基亚砜和二个双希夫碱，中心离子被双希夫碱桥联，组成一维无限长链。The complex of yttrium(Ⅲ) nitrate with N,N′ disalicyclideneethylene diamine, dimethyl sulfoxide was synthesized.The molecular structure of the complex was determined by X ray diffraction method.The crystal is monoclinic with space group P2 1/n , a=0.9631(2)nm,b=1.6415(5)nm,c=1.6209(3)nm,β=102.98(2)°,Z=4,Dx=1.653Mg.m -3 .The coordination number of Y(Ⅲ) is 9 with the geometry of a monocapped square antiprism. All of coordination atoms are oxygen atoms from three bidentate nitrate groups, two dischiff base molecules and one DMSO molecule. The two yttrium atoms were bridged by the dischiff base, resulting in an infinite chain.
