We report a new approach for the synthesis of heterohexa- and heterodecametalates via the use of non-aqueous, microwave-assisted reaction conditions. The two novel molybdovanadates have been isolated and characterized in the solid and solution states using single-crystal X-ray diffraction, FT-IR, UV/Vis, multinuclear NMR spectroscopy, and ESI-MS. The relative stabilities of the possible structural isomers were probed using dispersion-corrected DFT calculations for both polyoxometalate systems. Six of one, ten of another: Two molybdovanadates are prepared by microwave reaction of a polymolybdate with a polyvanadate. Both heteropolyoxometallates were isolated and characterized in the solid and solution state. The relative stabilities of their structural isomers were determined theoretically.
