Synthesis and structural characterisation of platinum silasesquioxane complexes

Abstract

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.
