The metal-rich sulfide Ta{sub 6.08}Nb{sub 4.92}S{sub 4} has been prepared by high temperature techniques and characterized by means of X-ray diffraction experiments. It crystallizes in the orthorhombic space group Pnma with four formula units in the cell: a = 3121.00 (54) pm, b = 335.07 (7) pm, and c = 959.18 (19) pm. Its structure is similar to that of niobium-rich sulfides, rather than to that of tantalum-rich sulfides. The metal coordinations are capped distorted cubic prisms and the coordinations of sulfur are capped trigonal prisms.
