The reaction of partially condensed silasesquioxanes of the type [R17Si7O9(OH)2(OR2)] (R1 = c-C5H9, c-C6H11; R2 = H, SiMe3) with either [Pt(dppe)(CO3)] or [Pt(dppe)Cl2]/Ag2O leads to the formation of [R17Si7O9(OR2)O2Pt(dppe)], crystallographically characterised for R1 = c-C5H9; R2 = SiMe3, providing unprecedented routes to late transition metal silasesquioxane complexes.
