| Abstract: | The MÖSSBAUER spectra of various samples of differently prepared SnII and SnIV iodides have been investigated. — An SnI2 sample, prepared by dissolving elemental tin in hydroiodic acid, was shown to be strongly contamined with SnI4; by recrystallisation from ethanol no purification was achieved. However, SnI2 samples being free from SnI4 were obtained by precipitation from SnCl2 solutions by means of HI, KI or NaI. The isomeric shift value of SnI2 is 3.8 mm/sec. — SnI4 may be easily prepared from metallic tin and elemental iodine in CHCl3 or py precipitation from an SnCl4 solution by means of HI or KI. |
