Abstract
A comparison of the asymmetric stretching frequency v3 and unit cell length a0 for a series of hexahalogeno-metallates A2MX6 [A = K+, Rb+, Cs+ and NH4+, M = Ru, Os, Sn and Te and X = Cl,Br] has been made. Trends observed for the tellurium and tin compounds may be related to stericfactors whereas possible M → X dπ-pπ bonding may explain the opposite trend found for ruthenium and osmium compounds.Keywords
