Comment on “Atomic force microscopy characterization of stable faces in cubic C60 single crystals”: Possible evidence for growth-promoting cross-twinning

An explanation is given for a molecular arrangement on a face of a C60 fcc single crystal as observed recently with atomic force microscopy (B. Keita et al., Chem. Phys. 179 (1994) 595). The explanation relies on a cross-twinning model of fcc crystal growth, and involves local fivefold symmetry.
