Abstract
A large number of the isomers of neutral and ionic Sn n (n=2–15) clusters have been designed and optimized at the level of MP2/LANL2DZ with the aid of the Gaussian 09 software package. The most stable geometric structures of ionic(cationic and anionic) Sn clusters have been compared with the corresponding neutral geometries. Most structures of Sn n + and Sn n are similar to each other except for the structures of those with n=5, 11 and 15; while the anions Sn n − are almost different from Sn n clusters with n=9–15 except for Sn12 − and Sn14 −. The electronic properties have been calculated, including binding energy, second difference in energy, HOMO-LUMO gaps, ionization potentials, and electron affinities.
