Notes:
The complete Raman spectrum of the pyramidal triiodostannate(II) ion [SnI3]- (ν1 = 162 cm-, strong, polarized; ν2 = 61 cm-, medium, polarized; ν3 = 148 cm-, strong, depolarized; ν4 = 48 cm-, strong, depolarized) is observed in a diethyl ether extract from a solution of tin(II) iodide containing hydriodic acid. Previous reports of the frequencies of [SnCl3]- are confirmed but for [SnBr3]- ν1 is revised from 211 to 205 cm-1. The complex acids H[SnX2Y] and H[SnXYZ] (X, Y or Z = Cl, Br or I) are observed in solvent extracts of tin(II) mixed halide solutions and a set of ν(Sn - halogen) frequencies is compiled. Appreciable co-extraction of [SnX2(H2O)] occurs at halogen acid concentrations below 3 mol l-1.
