摘　　要：报道了合成的九种稀土硝酸盐与精氨酸的配合物，经化学分析和热重分析确定了其组成为ＲＥ（ＮＯ３）３（Ａｒｇ）２·４Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｎｄ，Ｓｍ，Ｅｕ，Ｇｄ，Ｔｂ，Ｄｙ，Ｔｍ，Ｙ）．测定了配合物的红外光谱。The nine coordination compounds of rare earth nitrates with L Arginine prepared from water are obtained. The composition and structure of compounds have been determined by chemical analysis, element analysis and thermogravimetris analysis. The general formula of these compounds is RE(NO 3) 3(Arg) 2·4H 2O(RE=La, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Y). IR spectra of the solid coordination compounds are described. The results show the carboxyl group of arginine coordinates to Ln(Ⅲ) inos.
