A novel Keggin polyoxotungstate-based 1∶1-type Cp*Rh2+ complex (Cp* = C5Me5), [Cp*Rh(DMSO)3]H2[(Cp*Rh)(α-1,4,9-PW9V3O40)]·3DMSO·0.5MeCN 2, was synthesized by reaction in MeCN–DMSO mixed solvent at 80 °C under nitrogen, of the α-Keggin-type 1,4,9-trivanadium-substituted polyoxotungstate (NBu4)4H2[α-1,4,9-PW9V3O40] 1 with [Cp*Rh(MeCN)3]2+. Characterization was performed with complete elemental analysis, TG/DTA, FTIR, and multiple (51V, 31P, 1H and 13C) NMR spectroscopies. Complex 2 contains two different types of Cp*Rh2+ groups; one is covalently bonded to the surface oxygen atoms of three edge-shared vanadium octahedra while the other is present as a DMSO-solvated counter ion. The composition of complex 2 is unique and can be compared with previous Keggin and Dawson polyoxotungstate-based organometallic complexes.
