摘要：

The ternary compound Cu3TaS4 has been investigated by means of X-ray powder diffraction and its structure has been refined by the Rietveld method. This compound is isostructural with the sulvanite mineral Cu3VS4, and crystallizes in the cubic P (4) over bar 3m space group (No. 215), Z = 1, with unit cell parameters a = 5.5145(1) angstrom and V = 167.70(1) angstrom(3). The refinement of 14 instrumental and structural parameters converged to R-p = 4.4%, R-wp = 6.8%, R-exp= 5.5% and S = 1.2 for 4501 step intensities and 33 independent reflections.
