The structure described by KAg3S2 crystallizes in the cubic Fd-3m space group. K(1) is bonded to six equivalent S(1) atoms to form distorted edge-sharing KS6 octahedra. Ag(1) is bonded in a distorted bent 150 degrees geometry to two equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
