description: In this work, previous recording of the reflection spectra of samples of PbSb2Te4 crystals were analyzed, and compared with the theoretical spectrum. Due to the presence of some optical features unexplained by the classical Drude-Lorentz theory, it was decided to conduct an X-ray diffractometric study using a Bruker D8 Advance diffractometer. The data obtained made it possible to explain some features on the Raman spectrum of the studied compound PbSb2Te4. The main result of the work is the conclusion that there are two different phases in the proposed single crystal, more precisely, groups of spatial symmetry, as well as the presence of an additional phase of the compound with copper during alloying. Thus, it was possible to achieve the set goal â to clarify the crystal structure of the compound.
