A novel disubstituted Lindqvist-type polyoxomolybdate [Te2Mo4O19]6− supporting two organic vanadyl moieties: Synthesis, characterization, and crystal structure of {[V(2,2-bipy)2]2(4,4-bipy)[Te2Mo4O19]}

The first example of disubstituted Lindqvist-type polyoxomolybdate {[V(2,2-bipy)2]2(4,4-bipy)[Te2Mo4O19]} has been synthesized hydrothermally, which consists of a novel Lindqvist-type polyanion [Te2Mo4O19]6− supporting two vanadyl moieties [V(2,2-bipy)2]3+, and a non-coordinating “guest” 4,4-bipys molecule.
