Keywords:AuSb2, RuS2, pyrite-type compounds, single crystal diffraction, Debye temperature

Precise structural analyses of various compounds with pyrite-type structure were performed by selecting single crystals from synthetic and natural mineral crystals. The measurements of Debye temperatures of the compounds will be reported as one of the usefulness of single crystal diffraction method. Certain regularities regarding structural stabilization and physical properties are found in pyrite-type compounds.
