The layer structures of H 8 Si 8 O 12 molecules on highly oriented pyrolitic graphite have been investigated by scanning tunneling microscopy. Two kinds of ordered assemblies of H 8 Si 8 O 12 monolayers are observed, with a unit cell of 6.5 Å × 6.5 Å and 7.2 Å × 9.4 Å, respectively. On the basis of the shapes and sizes of the H 8 Si 8 O 12 STM images and the heights of the H 8 Si 8 O 12 monolayers, H 8 Si 8 O 12 can be adsorbed with one face of its cage structure in contact with the substrate surface or with a tilted orientation.
