Within the fullerene family of molecules, C20 is the smallest member. Due to the large strain energy imposed by the 12 adjacent carbon pentagons, C20 is highly unstable. In order to stabilize the caged structure for possible experimental synthesis, a series of atoms have been bonded to the carbon cage exohedrally. On page 925, Vivian B. Gomez and Kyle A. Beran investigate the energetic stability of C20 derivatives in terms of the relative physical, electronic, and thermodynamic properties of exohedral derivatives of the C20 fullerene.
