characterized by X-ray crystallography and 1H, 31P, 29Si, and 13C NMR spectroscopy. The crystal structures of 3a and 3b show a square-planar coordination around the Pt center bonded to Ph, PPh3, and bidentate O,O-coordinated silsesquioxane. One of the coordinated oxygen atoms is also bound to the AgPPh3 group.
