摘　　要：合成了四种轻稀土盐酸盐与Ｌ－组氨酸的配合物，经化学分析、元素分析和热重分析确定其组成为ＲＥＣｌ３（Ｈｉｓ）３·８Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ）．测定了配合物的红外光谱，并推测配体是通过羰基配位的．Four coordination compounds of light rare earth chlorides with Lhistidine prepared from water are obtained. The composition and structure of the compounds have been determined by chemical analysis, element analysis and thermogravimetris analysis. The general formula of these compounds is RECl3(His)3·8H2O(RE=La, Ce,Pr,Nd). IR spectra of the solid coordination compounds are described. The results show the carboxyl group of histidine coordnates to Ln(Ⅲ) inos.
