The work presents Raman spectra of platelike crystals of the CuCrS2 compound, which were grown from
polycrystalline CuCrS2 by the CVD method with an elementary iodine as a carrier. The spectra are
measured in the temperature range of 5-300 K. Observed vibrational modes are assigned based on the
temperature dependences of their frequencies. In the temperature range of magnetic ordering (Т ≤ 40 K)
a weak increase is observed in the frequencies of totally symmetric vibrations, which is interpreted as
a result of the phonon-magnon interaction.
