摘　　要：本文以氯化稀土ＲＥＣｌ３·ｎＨ２Ｏ（ｎ＝６）与二茂铁亚甲硫基乙酸钠Ｌ（Ｌ＝ＦｃＣＨ２ＳＣＨ２ＣＯＯＮａ）在无水乙醇中反应，合成了镧、钕、钐、铒四种新的配合物。通过元素分析、摩尔电导、红外光谱、紫外光谱、差热－热重等手段对配合物进行了研究，确定了配合物的组成为［ＲＥＬ３］·ｎＨ２Ｏ（ＲＥ＝Ｌａ、Ｎｄ、Ｓｍ、Ｅｒ，ｎ＝１或４）。配合物中配体的羟基以双齿螯合形式与稀土配位，硫也参与配位，配合物可能的配位数为９。In this paper ferrocenylmethylene sulfenyl acetic acid (Fc CH2SCH2COO-=L)as a new ligand and four complexes of the rare earth with L have been synthesised.The results of element and DTA-TG analysis indicate that the complexes formulate as REL3· H2O (RE= La,Nd ,Sm)and REL3·4H2O(RE=Er). The complexes have been studied by means of molar conductivity measurment, FT-IR and UV spectra. The IR spectra show that three carboxyl groups in complex coordinate with rare earth through the oxygen atom and the carboxyl groups are all bidentat chelate ligand. In addition sulphur atom also coordinate with rare earth. The possible ligancy of complexes is nine.
