摘要
The first example of disubstituted Lindqvist-type polyoxomolybdate {[V(2,2-bipy)(2)](2)(4,4-bipy)[Te2Mo4O19]} has been synthesized hydrothermally and characterized by elemental analyses, XPS, IR, TG-DTA and X-ray single crystal diffraction. The structural analysis shows that the neutral molecular unit [V(2,2-bipy)(2)](2)[Te2Mo4O19] consists of a novel Lindqvist-type polyanion [Te2Mo4O19](6-) supporting two vanadyl moieties [V(2,2-bipy)(2)](3+), and such neutral molecules are joined together by pi-pi stacking interactions between the pyridine groups to form a two-dimensional grid-like network with non-coordinating "guest" 4,4-bipys encapsulated.
