Adsorption of C 60 on the highly anisotropic Au(110) 1 × 2 reconstructed surface leads to an ordered quasi hexagonal 6 × 5 superstructure. This interfacial reconstruction has been investigated by grazing incidence X‐ray diffraction. Analysis of the in‐plane data set reveals four C 60 molecules per (6 × 5) unit cell with a separation between them close to 10 Å and a surface symmetry having a glide plane normal to [001]. The basic features characterizing the surface morphology of this reconstruction have been distinguished applying the ‘direct methods’ sum function. The arrangement of C 60 in the surface unit cell as well as the substrate distortion's map have been obtained from the analysis of the data at different resolutions which agree with STM measurements.
