Materials Data on KAg3S2 by Materials Project
KAg3S2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. K1+ is bonded to six equivalent S2- atoms to form edge-sharing KS6 octahedra. All K–S bond lengths are 3.29 Å. Ag1+ is bonded in a distorted bent 150 degrees geometry to two equivalent S2- atoms. Both Ag–S bond lengths are 2.47 Å. S2- is bonded in a 6-coordinate geometry to three equivalent K1+ and three equivalent Ag1+ atoms.
