Abstract

The structures and stability of isomeric vicinal dihyrides of $C_{70}$ are computed at the MNDO level.Their predicted stability is interpreted by comparing their electronic and molecular structures with those of $C_{70}$. While the two most stable isomers correspond to those obtained by hydrogenating the two most electron-rich bonds in $C_{70}$, the variations in the relative stability of the other isomers do not strictly parallel the bond orders of the bonds being hydrogenated. Changes in angle strain and the extent of \pi reorganization accompanying hydrogen addition are suggested to control the relative stability of the $C_{70}H_2$ isomers.
