Confirmation of the Crystal Structure of Tetrahedrite, Cu12Sb4S13.
The crystal structure of tetrahedrite, proposed in 1934 by Pauling and Neuman, has been confirmed. Least-squares refinement reduced the initial disagreement factor from 27.9 to 4.9 percent. Antimony displays three short orthogonal bonds to sulfur atoms. Two types of copper are tetrahedrally and triangularly coordinated by sulfur, respectively.
