Electronic structures of the icosahedral C&H,,, hydrocarbon and its perfhroro analog, C6nF6,,, are examined at the HF/4-31G and HF/6-3 lG\*\* levels. The calculated C-C bond lengths are as large as 1.57 A in C63Hb0 and 1.63 A in CbDF60. The bond lengthening is attributed to the H-H and F-F steric in

Single crystals of pure C6o are grown from the vapour phase. The crystal morphology is compared to the theoretical equilibrium form, predicted on the basis of a periodic bond chain analysis and a statistical mechanical approach. Some interesting growth phenomena are observed and discussed.
The electronic structure of Ca@Cso in the gas phase was probed by ultraviolet photoelectron spectroscopy (UPS) ofCa@CG. The electron affinity of Ca@C, was found to be 3.0 eV. The spectrum suggests that Ca donates its two 4s electrons to the Cm t,. LUMO. Ab initio self-consistent field Hartree-Fock c
A new ring-stacking model is proposed for preferential generation of C6o with lh symmetry and C7o with Dsh symmetry in carbon soot. The model is constructed on the basis of the following two assumptions: ( 1 ) A carbon closed cage (fullerene) is formed by a sequential stacking with appropriate numbe
