The compounds Cu₃SeTe were synthesized, the crystal structure and atomic dynamics were studied. As a result of X-ray diffraction studies, it was determined that the crystal structure of this compound corresponds to the cubic symmetry of the space group P-43 m. The studies of atomic dynamics were carried out by the method of Raman spectroscopy in the frequency range ν = 0–800 cm−1. It was found that the Raman modes obtained at frequencies ν = 41.56, 91.47, 119.83, 139.51, 208.18 and 266.41 cm−1 correspond to vibrations of metal–chalcogen and chalcogen–chalcogen bonds.
