By means of scanning tunneling microscopy we have studied the growth of C 60 on the Cu͑110͒ and Ni͑110͒ surfaces. A surprising difference in the C 60 structures formed is observed, despite the fact that the two ͑110͒ surfaces geometrically possess a high degree of similarity. On Cu͑110͒ C 60 forms the expected close-packed hexagonal overlayer, whereas C 60 induces a restructuring of the Ni͑110͒ surface. The surprising difference between the Cu and Ni surfaces is tentatively explained within a simple model, based on the interaction between the molecular orbitals of C 60 and the narrow d bands of the surface. ͓S0163-1829͑97͒04116-7͔
