摘要： 本文报道14种稀土元素和L-半胱氨酸(L-cys)的固态配合物,(RE(cys)3Cl3·3H2O,RE=Ce-Lu、Y,Pm除外),并根据它们的红外光谱和XPS能谱对配合物的配位方式进行了讨论。
关键词: 稀土配合物, L-半胱氨酸, 红外光谱, XPS能谱
Abstract: Fourteen complexes of rare earth trichloride with L-cysteine were preparecd from aq. ethanol solution (Cc complex from aq. n-butanol) at pH3.5. The compounds have structu-ral formula RE(cys)3Cl3·3H2O(RE=Cc-Lu and Y,except Pm). The main infrared absorption bands have been assigned. All the compounds may be classified into three groups: (1) complex of Ce which is a chain polynuclear complex with bridging bidentate ligand;(2)complexes of Pr-Ho and Y which are mononuclear complexes containing unidentate and che-lating bidentate ligands;(3) complexes of Er-Lu are the polymer containing unidentate,chelating bidentate and chelation-bridging tridentate ligands. Ln-O stretch vibration were observed at 412-428cm-1 and 169-197cm-1 The XPS study of Er-Lu complexes shows that the atoms of oxygen are coordinated to lanthanide ions. but chloride anions are not coordinated.
Key words: Rare carth complex, L-cysteine, FT-IR, XPS
