High-pressure studies of tin tetraiodide SnI<SUB>4</SUB> are reviewed. Recent x-ray diffraction studies have shown that SnI<SUB>4</SUB> undergoes successive phase transitions from an insulator crystalline phase (I; Pa3) to a metallic crystalline phase (II) at 7 GPa, to the amorphous state at about 15 GPa, and to a non-molecular crystalline phase (III; Fm3m) at 61 GPa. The crystal structure of phase III has been determined to be a substitutional disordered structure in which both iodine and tin atoms are randomly located at the fcc sites.
