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
