Stable phase CuIn 1− x Fe x S 2 ( x ≤ 0.10) crystals of chalcopyrite structure were prepared by annealing synthesized CuIn 1− x Fe x S 2 material with the new quasicubic structure of sphalerite type at the high pressure of 5.5 GPa and temperatures ranging from 1170 to 1270 K. CuIn 1− x Fe x S 2 solid solutions were formed by mixing of CuInS 2 and CuFe 1.02 S 1.98 that were synthesized in advance. Phase formation in the (1 − x )CuInS 2 – x CuFeS 2 system was investigated and the unit‐cell parameters (the lattice constants and the unit‐cell volume) were computed as a function of composition. In addition, the parameter of the tetragonal distortion ( c /2 a ) for CuIn 1− x Fe x S 2 solid solutions of chalcopyrite structure was determined.
