The material structure described by Rb2Ag2GeS4 crystallizes in the monoclinic C2/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to two equivalent Ag(1), two equivalent S(2), and four equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent Rb(1) and two equivalent S(1) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent S(2) atoms. Ge(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 one Rb(2), two equivalent Rb(1), one Ag(1), and one Ge(1) atom to form a mixture of distorted corner and edge-sharing SRb3AgGe square pyramids. In the second S site, S(2) is bonded in a 6-coordinate geometry to one Rb(1), two equivalent Rb(2), two equivalent Ag(2), and one Ge(1) atom. is represented by the CIF card [CIF]
