| Abstract: | REL3·nH2O( RE=La-Gd,n=1;RE=Y,Tb-Lu,n=4;HL=o-HOC6H4CO2H) were synthesized.Their thermal decomposition and IR spectra were studied.The crystal structures of the complexes of cerium and terbium were determined by X-ray diffraction method.They crystallize in the monoclinic space group P21/n ( CeL3·H2O) and Cc ( TbL3·4H2O),respectively,and show infinite chain structures.The coordination numbers are nine (Ce3+)and eight (Tb3+) respectively. |
