【摘要】 <正>2,2’-联咪唑(H2biim)具有一定的还原性和配位能力,能以多种形式与过渡金属配位,但在多金属氧酸盐(POMs)体系中易沉淀,很难将其引入POMs体系[1,2],尤其对于氧化性较强的Dawson型POMs更加困难。以单缺位Dawson结构钨磷酸盐{P2W17}为前驱体,在水溶液中引入Cu-H2biim配合物,构筑了双支撑型饱和更多还原

【Abstract】 2,2 -biimidazole has versatile coordination behavior and applications in many fields, but it is hard to be introduced into POM systems due to its weak reduction ability and coordination properties [1,2] . Using {P2W17} as a precursor, a bi-supported saturated Dawson-type tungstophosphate [Cu(H2biim)2(H2O)][{Cu(H2biim)2}2(P2W18O62)]·11H2O(1) was built in aqueous solution. 1 contains an isolated [Cu(H2biim)2(H2O)]2+ and a [{Cu(H2biim)2}2(P2W18O62)]2- anion. A 3-D structure (Fig. 1) was constructed by electrostatic and hydrogen bonding interactions.更多还原
