Abstract

A novel Keggin polyoxotungstate-based 1:1-type Cp*Rh2+ complex (Cp*=C5Me5), [Cp*Rh(DMSO)(3)]H-2[(Cp*Rh)(alpha -1,4,9-PW9V3O40)]. 3DMSO .0.5MeCN 2, was synthesized by reaction in MeCN-DMSO mixed solvent at 80 degreesC under nitrogen, of the alpha -Keggin-type 1,4,9-trivanadium-substituted polyoxotungstate (NBu4)(4)H-2[alpha -1,4,9-PW9V3O40] 1 with [Cp*Rh(MeCN)(3)](2+). Characterization was performed with complete elemental analysis, TG/DTA, FTIR,and multiple (V-51, P-31, H-1 and C-13) NMR spectroscopies. Complex 2 contains two different types of Cp*Rh2+ groups; one is covalently bonded to thesurface 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.
