Abstract:The structures of cluster X@Si20 H20 as well as endohedral complexes X@Si20H20 and X@ Si20 H20 ( X = N, P, As, C^-, Si^- ) have been studied at the B3LYP/6-31G(d) level of density functional theory (DFT). The geometries, vibrational frequency and energetic parameters were discussed at the same level. It is found that the endohedral X@Si20H20(X = N, P, As, C^-, Si^- ) complexes are the global minimum.
Keywords:structure and stability  inclusion energy  deformation energy
