| Redox coupling of polyoxovanadates in non-aqueous solvent under mild conditions may be suitable for conversion of certain series of polyoxovanadates into larger species. With the utilization of redox chemistry of vanadium, the isolation of a series of reduced polyoxovanadates with reductive coupling have been investigated. Alternatively, the oxidative coupling of polyoxometalates may be possible for the synthesis of fully oxidized polyoxovanadates. The nucleophilic reduced species and electrophilic V(V) species produced by the controlled oxidation may prompt to couple two species into a larger polyoxovanadate. By the addition of template anions to the condensation reaction, we isolated a spherical triacontavanadate (V30) with V(V) oxidation state. |
