摘要
本文用改进的方法首次合成出 K_6[Z(H_2O)MnW_(11)O_(39)]·xH_2O(Z=N_(i),Zn),K_(13)[Ln(MnW_(11)O_(39)_2)]·yH_2O(Ln=La,Nd).通过化学分析、离子交换、IR、UV、XPS 等方法对合成产物进行了鉴定.在此基础上对其热性质和在溶液中的某些性质进行了研究.热分析实验表明,11-钨锰杂多阴离子为配体的配合物比饱和的 Keggin 结构12-钨锰杂多配合物具有较高的热稳定性.
In this paper,the complexes K_6[Z(H_2O)MnW_(11)O_(39)]·xH_2O(Z=Ni,Zn), K_(13)[Ln(MnW_(11)O_(39)_2]·yH_2O(Ln=La,Nd)has been first prepared by an improved method.We have examinated the synthetic product by the chemical analysis,ionic ex- change,IR,UV,XPS.According to these,we have studied their thermal property as well as some properties in the solution.The thermal analysis incated that the complexes with 11-tungstomanganate heteropolyanion as ligand had higher thermal stability than that of saturated Keggin structure 12-tungstomanganate.
