Making one VIV substitution for Mo on classical [MoV2O4]2+ group: the first heterobimetallic Mo–V subunit in polyoxomolybdate–bisphosphonate family

The first molybdovanadate cluster modified by bisphosphonate ligand with a new [Mo V V IV O 4 ] building unit is successfully synthesized. The VO bonds in this compound are demonstrated to play a pivotal role in the deep oxidation of dibenzothiophene.
