摘要：The ternary Cu3TaS4 compound crystallizes in the cubic P 3m space group (Nº 215), Z = 1, with a = 5.5145(1) Å, V = 167.70 (1) Å3. Its structure was refined from X-ray powder diffraction data using the Rietveld method. This compound is isostructural with the sulvanite mineral, Cu3VS4, and is characterized for a three-dimensional arrangement of CuS4 and TaS4 tetrahedra connected by common edges.
