description: The object of the study is samples of layered chalcogenide - lead-antimony telluride (PbSb2Te4). The aim of the work is to clarify the structure and to explain some optical properties of these crystals using X-ray diffraction methods. In this study, the reflection spectra of PbSb2Te4 crystal samples were recorded, analyzed and compared with the theoretical spectrum. Due to some optical features that could not be explained by the classical Drude-Lorentz theory, an X-ray diffraction study was conducted using a Bruker D8 Advance diffractometer. The obtained data also allowed us to explain some features in the Raman spectrum of the studied compound PbSb2Te4. The main result of our work is the finding that there are two different phases present in the proposed single crystal. More specifically, we identified groups of spatial symmetry within the crystal. This allowed us to achieve our goal of clarifying the crystal structure of the compound.
