The crystal structure described by Rb2AgSbS4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 7-coordinate geometry to one S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. Ag(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form distorted AgS4 tetrahedra that share corners with two equivalent Sb(1)S4 tetrahedra and  an edgeedge with one Sb(1)S4 tetrahedra. Sb(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form SbS4 tetrahedra that share corners with two equivalent Ag(1)S4 tetrahedra and  an edgeedge with one Ag(1)S4 tetrahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Rb(2), one Ag(1), and one Sb(1) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Ag(1), and one Sb(1) atom. In the third S site, S(3) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Ag(1), and one Sb(1) atom. In the fourth S site, S(4) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Ag(1), and one Sb(1) atom. is represented by the CIF card [CIF]
