摘要
三缺位单元构筑的金属氧簇化合物拓宽了多酸化学的发展方向,丰富了多金属氧簇在催化、磁性能方面的应用。{SbW_9}是一种三缺位构筑基本单元,通过引入过渡金属、稀土金属、有机物及有机金属基团实现共价键作用力、离子键或非共价键作用力修饰,得到结构多样、性能优异的新型簇化合物,但针对{SbW_9}夹心结构构筑多金属氧簇综述类研究鲜有报道。总结了已报道的111例基于{SbW_9}单元构筑的多金属氧簇化合物,对其结构、合成策略及影响因素进行分析,简述其在催化、磁性、生物医药等方面的应用,并对{XW_9}缺位单元构筑多金属氧酸盐的发展前景进行了展望。该综述对结构拓展、高核簇构建具有一定意义。
The research of trivacant unit has broaded the field of polyoxometalates and widened the applications of catalysis and magnetism. The trivacant Keggin {SbW_9} unit is an excellent building block, which can be used to prepare novel compounds with diverse structures and excellent performances by the introduction of transition metal, rare earth metal, organometallic and other groups connected through covalent, ion bonding or noncovalent interactions, but the review of trivacant polyoxotungstate is rarely reported. In the review, 111 compounds based on {SbW_9} unit have been illustrated and discussed about structural diversities, synthetic methodologies and main influencing factors. In addition, related applications have been shown such as catalysis, magnetism and biological medicine. Finally, it is prospected that the research prospect of polyoxometalate based on lacunary polyoxoanions.The review has a significant effect on expanding structure and building multi-core clusters.
