The synthesis of W₃S₄Cl₄, a layered tungsten thiohalide with a basic structure similar to TiS₃ is described. W₃S₄Cl₄ was synthesized from WCl₂ and sulfur at 350°C. The X-ray powder diffraction pattern was completely indexed on a small hexagonal unit cell with a = 3.336(1) A and c = 5.907(1) A. Electron diffraction studies revealed a 4 × 4 × 8 supercell, giving the compound a superstructure with a = 13.356 A and c = 47.29 A. An ordering of the tungsten vacancies which can account for this superstructure is discussed in light of the electron diffraction patterns.
