FT-Ir Studies of Decarbonylation and Recarbonylation of (Pt-3(Co)(6))(2)(5) Supported on Dehydrated SiO2
Decarbonylation of [Pt-3(CO)(6)](5) on SiO2 at 373 K produced [Pt-3(t-CO)(3)](5) species, where all the terminal CO remained. Complete decarbonylation at 423 K was not observed, which led to aggregation at 473 K. The interaction of some Pt with SiO2 inhibited complete recarbonylation to [Pt-3(CO)(6)](5).
