Rb4Au6S5 crystallizes in the hexagonal P-62c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 11-coordinate geometry to six equivalent Au(1), two equivalent S(2), and three equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. Au(1) is bonded in a 4-coordinate geometry to three equivalent Rb(1), one S(1), and one S(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 7-coordinate geometry to two equivalent Rb(2), three equivalent Rb(1), and two equivalent Au(1) atoms. In the second S site, S(2) is bonded to three equivalent Rb(1) and three equivalent Au(1) atoms to form face-sharing SRb3Au3 octahedra.
