Popis: Tetramethyl tin reacts with dodecatungstosilicic acid H 4 SiW 12 O 40 in anhydrous DMSO with evolution of methane to yield the trimethyl tin salt of the heteropolyoxometalate [α-SiW 12 O 40 ][(CH 3 ) 3 Sn(DMSO) 2 ] 4 · 2DMSO. The structure has been determined by X-ray diffraction and shows that there is no direct bond between the polyoxometalate and the tin complex. 119 Sn NMR indicates that tin has quite the same coordination in the solid state and in DMSO solution.
