The rhombohedral low-temperature phase of the Cu 4Se 1.5Te 0.5 (α) with lattice constants a=4.162Å, c=20.66Å, sp. gr. R-3m, Z=3, was investigated by high temperature x-ray diffraction methods, in a vacuum. It was established that this α-phase is a three-package polytype of the structure β-Cu2Te and at 558 K reversible transformed into a cubic phase, with lattice constants of a=5,899Å. © 2011 American Institute of Physics.
