The reaction of silica-supported bis(allyl)rhodium, (≡SiO) (≡SiOX(Rh(η3-C3H5)2 1 (X = H, Si≡) with PMe3 followed by H2 yields [RhH 2(PMe3)4]+, 2, which is characterised by IR, solid-state 31P NMR and elemental analyses and extracted quantitatively from the surface by ion-exchange with Bu n4NCl in nitromethane; the counterion of 2 is presumed to be a siloxy group [≡SiO]- of the silica surface.
