The compound described by Rb3SbS4 crystallizes in the orthorhombic Pnma 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(3), two equivalent S(2), and four equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to two equivalent S(2), two equivalent S(3), and three equivalent S(1) atoms. Sb(1) is bonded in a tetrahedral geometry to one S(2), one S(3), and two equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), three equivalent Rb(2), and one Sb(1) atom. In the second S site, S(2) is bonded in a 7-coordinate geometry to two equivalent Rb(1), four equivalent Rb(2), and one Sb(1) atom. In the third S site, S(3) is bonded to one Rb(1), four equivalent Rb(2), and one Sb(1) atom to form edge-sharing SRb5Sb octahedra. is represented by the CIF file [CIF]
