摘要
采用直接法制备了主族金属元素铅取代的以锰为中心原子的杂多配合物,经ICP,TG曲线确定其化学式为K14[Pb(MnW11O39)2].49H2O,采用IR,XRD,183WNMR等手段对配合物结构进行了表征,表明配合物具有Keggin结构.同时对配合物的热稳定性进行了讨论。
Adopt direct method to produce the main group metal element-lead to take the place of heteropoly compounds with Mn as the central atom. By means of ICP and TG, the molecular formulas were confirmed as K14[Pb（MnW11O39）2]·49H2O. Compounds were characterized by IR, XRD and ^183WNMR, confirming compounds were Keggin structure. The while their thermal stabilities were discussed.
