摘要：

Organically modified 'Keggin-type' oxopolymetalates of general chemical formula [R]4[SiW11O40(SiR")2], (R = H+, K+ or NR'4+; R' = Me or Bu; R" = Et, CH = CH2, C10H21 or Ph) have been synthesised by three different procedures. Large quantities were obtained in high purity and good yield. Their structure has been established by a multispectroscopic study, elemental mass analysis, and time of flight spectrometry (Cf-252). Selection rules governing the latter technique are also detailed. IR, Si-29 and W-183 NMR spectroscopy confirm that two organic silicon groups are bonded to the surface of the lacunar SiW11O38(8-) heteropolyoxometalate.
