The semiconductor compounds AgInVI2 (VI: S, Se, Te) crystallize in the chalcopyrite structure with space group I2d. These compounds have received considerable attention because they show promising electrical and optical properties for solar cell devices. We report on a structural analysis of AgInTe2 polycrystalline samples by using the high-energy powder diffraction technique. The experiments were performed at a pressure of P = 2.7 kbar at the DW11 station, LURE Orsay, France. The analysis of the experimental data was performed with EDX, DICVOL 91 and NBS-AID-93 programs. The structure of AgInTe2 was indexed in the tetragonal system with space group I2d. The obtained lattice parameters were a = 6.262(3) Å and c = 12.897(2) Å. These results confirm the existence of a previously reported chalcopyrite phase for AgInTe2.
