The two low-energy isomers of C{sub 61}H{sub 2} are the parent molecules of fulleroids and methanofullerenes. We present a thorough study of their structural and electronic properties within the density functional theory, in the local-density approximation and also including gradient corrections to the exchange and correlation functionals. Calculations are performed both on the isolated molecules and on the solid phases. Changes with respect to C{sub 60} as well as differences between the two C{sub 61}H{sub 2} isomers are described with regard to geometrical characteristics, bond patterns, valence charge distribution, and electronic energy bands. Our results can be considered a paradigm for the study of fulleroids and methanofullerenes. 37 refs., 7 figs., 6 tabs.
