Abstract—The H₂[Pt₃(CO)₆]₅ + SnCl₂ reaction solutions and the precipitates isolated from these solutions were
studied by IR and Mössbauer spectroscopy and NMR. At any initial reagent ratio in the range [Sn] : [Pt] = 1–5,
the reaction yields a Pt–Sn–CO cluster with the atomic ratio Sn : Pt = 1 : 1. The adsorption properties of the
platinum–tin–carbonyl cluster were examined. Strong adsorption of the cluster on -Al₂O₃ and its high stability
in contact with the supporter allow to use it as a precursor of supported bimetallic Pt–Sn/-Al₂O₃ catalysts and
to prepare catalysts of the adsorption type of definite compositions.
