The high-pressure cubic metallic form of indium telluride, InTe(II), transforms at 1 atmosphere to a new transitory polymorph, designated InTe(II'), which, in turn, transforms to the stable tetragonal polymorph InTe(I). The new polymorph is apparently tetragonal with unit-cell dimensions a0 = 6.06 Å, c0 = 6.55 Å. The transformation rates of InTe(II) to InTe(II') and of InTe(II') to InTe(I) are dependent on both time and temperature; the former is very rapid above 60°C and the latter is very rapid above 125°C.
