本文报道了一种新的三缺位杂多阴离子α-[GaW_9O_(34)H_2]~(9-)的钠、钾、四甲基铵盐的合成方法,并通过元素分析、红外、紫外、极谱、热分析等方法对它进行了表征。α-[GaW_9-O_(34)H_2]~(9-)是一具有三个空位的杂多阴离子,它能与过渡金属离子反应生成具有Keggin结构的三取代钨镓杂多阴离子[GaW_9O_(37)M_3(H_2O)_3]~(R-)。
In this paper, a novel method for the synthesis of sodium, potassium and tetramethylammonium salts of trivalent anions [GaW_9O_ (34) H_2] ~ (9-) has been reported. Polarographic, thermal analysis and other methods to characterize it. α - [GaW_9-O_ (34) H_2] ~ (9-) is a heteropolyanion with three vacancies which can react with transition metal ions to form trisubstituted tungsten gallium heteropolyanion [GaW_9O_ (37) ) M_3 (H_2O) _3] ~ (R-).
