摘要： 合成了两种不同晶形的配合物,其组成分别为[Ho2(o-HOC6H1CO2)6(H2O)4]·4H2O及[Ho(o-HOC6H4CO2)3·(H2O)2·2H2O]n,用X射线衍射法测定了它们的结构：一种以二聚体形式存在,属三斜晶系(Ⅰ),其中钬离子的配位数为9;另一种呈无限链状聚合结构,属单斜晶系(Ⅱ),钬离子的配位数为8.同时还研究了它们的热分解过程。

Abstract: Two complexes with the same composition Ho(o-HOC6H4CO2)3·4H2Owere synthesized, and their crystal structures were determined by X-ray diffraction method.(Ⅰ) is the triclinic dimer with the coordination number of nine, and(Ⅱ) belongs to the monoclinic system having an infinite polymeric chain structure with the coordination number of eitht.The thermal decomposition processes of the two complexes were also studied.
