摘要： 对3种过渡金属钨硅杂多酸钾盐的组成及性质进行了研究,与12-钨硅酸钾比较表明,在Keggin阴离子骨架中,以空位或过渡金属Mn2+、Co2+、Ni2+取代一个W6+后,其W—O、Si—O键振动吸收频率、组成元素内层电子结合能、W—O多面体的可还原性、晶形、晶格大小及热稳定性都出现了明显变化,这些变化与过渡元素的性质相关联.

关键词: 钨硅杂多化合物, 过渡金属, 空位

Abstract: Five heteropoly silicotungstic compunds were synthesized.Their properties were characterized.The results indicate that the IRabsorption of W-Oc-W and Si-O bonds,the electronic bonding energy of constituent elements,the reducibility of W-Opolyhedra,the lattice size and crystal shape of heteropoly compound and the thermal stability of Keggin unit etc.are changed obviously,when Watom in Keggin anion was substituted for a alcunary or a lower valence transition metal ion such as Mn2+,Co2+ and Ni2+.In the paper,the correlation of the properties of the transition metals with the changes mentioned above was discussed.

Key words: Heteropoly silicotungstic compound, Transition metal, Lacuna
