Abstract

A new copper thioborate, CuBS₂, was synthesized at high-pressure/temperature condition of 3 GPa and 700-900 °C. The crystal structure was refined by the Rietveld analysis of the powder X-ray diffraction data. The compound crystallizes into a tetragonal unit cell (a = 0.5044(1) nm, c = 0.8947(2) nm, space group: I-42d), isostructural with CuMS₂ chalcopyrite compounds (M: Al, Ga, and In). The compound is the first representative of the chalcopyrite-type family consisting of BS₄-tetrahedra. From the UV-Vis diffuse reflectance spectrum, the optical band gap of CuBS₂ was estimated to be E_g = 3.61 eV.
