Protonation of Cp(PMe3)2RuSiCl3 (1) leads to the formation of [Cp(PMe3)2Ru(η2-HSiCl3)]+ (2+), a rare example of a cationic η2-silane complex. The η2-silane coordination in 2+ is confirmed by an X-ray crystallographic study. The short Ru−H and long Si−H interactions in 2+ model the latter stages of hydrosilane oxidative addition to a metal center.
