Abstract

The synthesis of W3S4Cl4, a layered tungsten thiohalide with a basic structure similar to TiS2 is described. W3S4Cl4 was synthesized from WCl2 and sulfur at 350-degrees-C. The X-ray powder diffraction pattern was completely indexed on a small hexagonal unit cell with a = 3.336(1) angstrom and c = 5.907(1) angstrom. Electron diffraction studies revealed a 4 X 4 X 8 supercell, giving the compound a superstructure with a = 13.356 angstrom and c = 4 7.29 angstrom. An ordering of the tungsten vacancies which can account for this superstructure is discussed in light of the electron diffraction patterns.
