Abstract
The unit cell of Ag7GeS5I, a member of the argyrodite family, is cubic face-centered with a = 1072.2(7) pm and Z = 4. The anion lattice consists of three-dimensionally connected Frank-Kasper polyhedra with C. N. 12 and 16. The silver ions are statistically distributed over a number of sites with C. N. 4, 3 and 2, formed by isolated GeS4-tetrahedra, as well as isolated S2−- and I− -ions.
