“…larizabilities in Table II were used to calculate the interaction constants in the interaction force constant, Q, and the van der Waals sums.Sy (Table III), using procedures described previously. 24 The calculations were performed assuming the following self-consistent charge distributions and Cl atom positions: for Cs2GeCl6, Cs= 14-, Ge = 0.802+, Cl = 0.467-, x = 0.2302; for K2SnCl6,K = 14-, Sn = 1.0+, Cl = 0.50-, x =0.2415; for Rb2PbCl6, Rb = 14-, Pb = 0.8984-, Cl = 0.483-, x = 0.2452. Table IV summarizes the results.…”
