Making one VIV substitution for Mo on classical [Mo V2O4]2+ group: the first heterobimetallic Mo–V subunit in polyoxomolybdate–bisphosphonate family

Abstract

The development of a library of basic building units with distinct compositional and structural characteristics for the preparation of polyoxometalates remains a challenging and attractive endeavor. Herein, the first molybdovanadate cluster (1) modified by bisphosphonate (BP) ligands in a new [MoVVIVO4] building unit is successfully synthesized based on one V substituting for one Mo in the classical [MoV2O4] building unit. To compare the catalytic oxidation activity of the V-doped molybdovanadate cluster to that of other molybdovanadate clusters without V[double bond, length as m-dash]O in an organic model reaction, a molybdovanadate cluster (2) free of V[double bond, length as m-dash]O was prepared and using the atomically precise 1 and 2 as catalysts confirms the significance of the V-replaced model containing V[double bond, length as m-dash]O. This work provides an insight into the assembly and catalytic activity site design of Mo–V clusters and enriches the basic building units of the polyoxomolybdate (POMos)–BP family.
