| 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)_3Cl_3.3H_2O(RE=Cc-Lu and Y,except Pm). The main infrared absorp-tion 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 wereobserved at 412--428cm~(-1) and 169--197cm~(-1) The XPS study of Er-Lu complexes showsthat the atoms of oxygen are coordinated to lanthanide ions. but chloride anions are notcoordinated. |
