Mixed Stannic Halides

Stannic chlorobromide, SnCl2Br2, was described by Ladenburg, and the three compounds, SnCl3Br, SnCl2Br2, and SnClBr3, by Besson; whilst Lenormand supposed that he had obtained SnCl3I, SnCl2I2, SnClI3, SnBr3I, SnBr2I2, SnBrI3 by the interaction of stannous halides and appropriate halogens or halogen hydracids; but it has been shown by Auger, by reference to their physical behaviour, that all these supposed compounds are probably mixtures.

Thus, mixtures of SnBr4 and SnI4 show a normal freezing-point curve, with a eutectie point at the composition SnBr3.2I0.8; and the supposed compound SnBr2I2, which melts at 54° C., is identical with an equimolecular mixture of SnBr4 and SnI4, and may be separated by ten fractional crystallisations into fractions melting at 88° C. and 27°C., having the compositions SnBr1.2I2.8 and SnBr2.7I1.3 respectively.

Similarly the supposed compounds SnBrI3 and SnBr3I may be partly resolved by crystallisation. Moreover, it is suggested that in all molten mixtures of the composition SnBrαI4-α the halogen atoms are perfectly mobile, and that the same is true for the chlorobromides and chloroiodides.
