"On the Crystal Structure of C36"
E. Burgos, E. Halac and H. Bonadeo
Chem. Phys. Lett. 320(1-2) (2000) 14-18
We present calculations which indicate that the newly synthesized C36 molecule probably forms a Van der Waals crystal, of rombohedral or hexagonal structure. Our results, based on intermolecular potentials of the atom-atom form, are in good agreement with the existing experimental evidence. Using covalent semiempirical potentials, we find that if molecules are placed closely together they tend to form extra bonds, several energy minima are thus obtained, but these correspond to structures with either too large or too short intermolecular distances in the basal plane.
