Abstract

It is shown that it is possible to graft organometallic fragments, namely Sn(C₄H₉)_x (x = 1,2,3) at the surface of a rhodium particle supported on silica. These organometallic fragments are obtained by selective hydrogenolysis of Sn(C₄H₉)₄ on a Rhodium/silica catalyst. They are thermally stable on the particle up to a temperature of 423 K. The surface organometallic fragments have been characterized by micro-analytical data. Electron microscopy (CTEM and STEM), infrared spectroscopy, XPS Analysis, Moessbauer spectroscopy, MAS ¹³C NMR, EXAFS and molecular modeling. Depending on experimental conditions, it is possible to propose various surface structures for the organometallic fragments. However, the most likely fragment can be represented by the general formula: Rh₈Sn[Sn(C₄H₉)₃]₂.
