The material structure described by RbAg2SbS4 crystallizes in the trigonal P3_221 space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent S(2) atoms. Ag(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent S(1) and two equivalent S(2) atoms. Sb(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Rb(1), two equivalent Ag(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing SRb2Ag2Sb trigonal bipyramids. In the second S site, S(2) is bonded in a 5-coordinate geometry to two equivalent Rb(1), two equivalent Ag(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
