摘要
合成了哌嗪的3种杂多金属氧酸盐(XY12O40n-,X=P、Si;Y=W、Mo)化合物,用元素分析,IR,TG-DTA-DTG等方法对标题化合物进行了表征.IR结果表明:这些化合物中均存在[C4H8N2H3]+,阴离子保持了Keggin结构;TG-DTA-DTG曲线显示它们的热分解是一个多步过程.
Three Heteropolyoxometalates of Piperazine with Keggin structure （XY12O40^n- , X = P,Si; Y=W, Mo） were synthesized and characterized by IR, TG-DTA and elemental analyses. The results showed that the presence of Keggin structure and organic cations [ NHC4H8NH2]^＋ in these compounds. The TG-DTA curves showed that their thermal decomposition was a multi-step process.
