【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。更多还原

【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.更多还原
