The surface structure and composition of the (001)- and (111)-oriented surfaces of the ordered Pt{sub 3}Sn alloy were determined by low-energy-electron-diffraction intensity analysis. For both orientations the surface structure corresponds to a bulk truncation model. For the (001) surface, the mixed PtSn'' plane forms the outermost surface layer. Sn atoms in the outermost plane are also significantly upwardly displaced (by about 0.2 A) for both the (001) and the (111) surfaces.
