An STM study of C 70 (sub‐)monolayers deposited at an n ‐tetradecane/Au(111) interface (see Figure) is reported. The adsorption of C 70 and C 60 are compared in the light of their geometric and electronic differences. While C 60 is a strained spherical cage, C 70 has a reduced symmetry and an ellipsoidal shape. The structural differences between the C 60 and C 70 (sub‐)monolayers are discussed in terms of commensurability between the adsorbate and the Au (111) lattices.
