| Abstract: | 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]2Te2Mo4O19] 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 π − π stacking interactions between the pyridine groups to form a two-dimensional grid-like network with non-coordinating “guest” 4,4-bipys encapsulated. |
