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MaHb[β-GaW9O34H]·xH2O(M=Na+,K+,NH4+,MeN+,Et4N+)的盐,并以β-(GaW9O34H]10-为母体,合成了M8H3[β-GaW9Mn3(H2O)3O37]·xH2O(M=Na+,K+)盐,通过IR、UV、极谱和CV、ESR、μerr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.

Abstract: 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-GaW9O34H]·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,μeff and DTA determinations.The results show that the title complex is reactive towards the coordination reaction and has a trivacance Keggin structure.
