Sn I Mössbauer effect / Electron microscopy / a 2 -Sn / ß 2 SaAbstract. a 2 -Sn, ß 2 -Sn and the solid-state transition of a 2 -Sn to ß 2 -Sn observed in tin grown by reduction of aqueous solutions of SnCl 2 with Mg are investigated by transmission electron microscopy (TEM) with selected area electron diffraction, Mössbauer spectroscopy and X-ray diffraction. Some data on the structure of two tin dioxides grown as additional products during the reduction of SnCl 2 with Mg and Al are included. The low sensitivity of the X-ray diffraction studies towards the a 2 -Sn and its derivates, and towards the unusual Sn0 2 structures is also discussed.
