Ionothermal Synthesis of an Antimonomolybdate Cluster, [Sb8Mo13VIMo5VO66]5-, and Its Catalytic Behavior to the Reduction of Nitrobenzene

The largest antimonomolybdate monomer, [(Sb8Mo13Mo5O66)-Mo-VI-O-V](5-) (1-Sb8Mo18), has been isolated and displays a new breakthrough of polyoxometalates (POMs) with an ionothermal synthesis strategy. 1-Sb8Mo18 features the first hexanudear sandwich-type polymolybdate (POMo) with an unexpected metal ring {Sb6O12} to make its debut in Sb clusters. Furthermore, 1-Sb8Mo18 exhibits a prominent catalytic activity for reducing nitrobenzene to aniline with excellent sustainability.
