摘要
本文报道了β-九-钨镓杂多阴离子的合成方法——配位平衡竞争法,首次合成了5种通式为(?)[β-GaW_9O_(34)H]·xH_2O(M=Na^+,K^+,NH_4^+,MeN^+,Et_4N^+)的盐,并以β-(GaW_9O_(34)H]^(10-)为母体,合成了M_8H_3[β-GaW_9Mn_3(H_2O)_3O_(37)]·xH_2O(M=Na^+,K^+)盐,通过IR、UV、极谱和CV、ESR、μ_(err)和DTA等方法对化合物进行了表征,证明标题化合物为三缺位、有配位反应活性和Keggin结构骨架的杂多化合物异构体.
A method----coordinating equilibrium competition----for synthesizing β-GaW9 heteropolyanion is reported here.The anion was separated in the form of salts with a general formula MaHb[β-GaW9O3.4H]·xH2O(M+=Na,K,NH4,Me4N,Et4N,a+b=10).The anion is the first β-isomer of Ga-containing heteropoly complexes and it can react with Mn2+ ion to form anion β-GaW9Mn3(H2O)3O3711-All the complexes prepared here are characterized by IR,UV spectra,CV,ESR,βeff and DTA determinations.The results show that the title complex is reactive towards the coordination reaction and has a trivacance Keggin structure.
