摘要
本文合成了以11-钨锰杂多阴离子为配体的4个配合物:K_6Z(H_2O)MnW_(11)O_(39)xH_2O(Z=ZD、Ni)和K_(13)Ln(MnW_(11)O_(39))_2·xH_2O(Ln=La、Nd)。用化学分析、离子交换、电导滴定、IR、UV、x-射线光电子能谱等进行了表征,还对其热性质等进行了研究。
K_6Z(H_2O)MnW_(11)O_(39)·xH_2O(Z = Zn, Ni)and K_(13)Ln(MnW_(11)O_(39))_2·xH_2O (Ln = La,Nd)were prepared and characterized by spectral and thermogravimetric analyses. The charge ofheteropolyanions in aqueous solution and their alkalinity was 13 as determined by conduc-tometric titration. The complexes are stable in aqueous solution of pH 3. 8 to 6.3.
