Abstract
The structures, stabilities, and electronic properties of the endohedral fullerene GeH4@C60 have been systematically studied by using the hybrid DFT-B3PW91 functional in conjunction with 6-31G(d) basis sets. Our calculated results show that the GeH4 molecule is more compact in the center of the C60 cage and exists in molecular form inside the fullerene. The Zero-Point and BSSE corrected binding energy of GeH4@C60 is −1.77 eV. The calculated HOMO–LUMO energy gap, the vertical ionization potentials (VIP) and vertical electron affinities (VEA) are similar to that of C60 cage. It is indicated that GeH4@C60 also seems to be very stable species. Natural population analysis on the GeH4@C60 reveals that the central GeH4 only gain −0.06 charges from the C60 cage. Additionally, the vibrational frequencies and active infrared intensities of GeH4@C60 are also discussed.
