| 摘要: 本文合成了邻羟基苯甲酸(o-HOC6H4CO2H)与十五种希土的配合物,测定了铈,铽的配合物晶体结构。二者均属单斜晶系,铈配合物空间群为P21/n。配位数为9,铽配合物空间群为Cc,配位数为8.两种配合物均呈无限链状聚合结构。 |

| 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. |
