Coupled-cluster calculations are reported for the electric and vibrational properties of the stannous halides SnX2 and stannic halides SnX4 with X = F, Cl, Br, and I. Comparison with experiment, where available, is made. Our best values of the static mean dipole polarizability for SnF2, SnCl2, SnBr2, and SnI2, are 39.98, 71.93, 91.37, and 125.8 atomic units, respectively. Our best values of the static mean dipole polarizability for SnF4, SnCl4, SnBr4, and SnI4, are 32.82, 93.04, 126.9, and 191.2 atomic units, respectively. (C) 2015 Elsevier B.V. All rights reserved.
