Abstract: The Cu$_2$CrSnS$_4$ microcrystalline powders and films with orthorhombic structure were obtained by solid-phase synthesis, and their Raman spectra were recorded for the first time. By optical spectroscopy, it was found that their $E_g$ = 1.70 eV, while in energy band gap of the powders there is a donor level with $E$ = 1.23 eV. It is shown for the first time that films of this material are photosensitive and have $p$-type of dark conductivity.

Keywords: solid-phase synthesis, microcrystalline powder, film, dark conductivity.
