The structure described by Rb4Re6S13 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 one S(1), one S(5), one S(6), one S(7), two equivalent S(2), and two equivalent S(3) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to one S(1), one S(2), one S(4), one S(5), one S(7), and two equivalent S(6) atoms. There are three inequivalent Re sites. In the first Re site, Re(1) is bonded to one S(1), one S(2), one S(3), one S(4), and one S(6) atom to form edge-sharing ReS5 square pyramids. In the second Re site, Re(2) is bonded to one S(1), one S(2), one S(3), one S(4), and one S(7) atom to form a mixture of distorted edge and corner-sharing ReS5 square pyramids. In the third Re site, Re(3) is bonded to one S(1), one S(2), one S(3), one S(4), and one S(5) atom to form ReS5 square pyramids that share  a cornercorner with one S(5)Rb2ReS tetrahedra, edges with two equivalent Re(1)S5 square pyramids, and edges with two equivalent Re(2)S5 square pyramids. There are seven inequivalent S sites. In the first S site, S(7) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Re(2) atoms. In the second S site, S(1) is bonded in a 5-coordinate geometry to one Rb(1), one Rb(2), one Re(1), one Re(2), and one Re(3) atom. In the third S site, S(2) is bonded in a 6-coordinate geometry to one Rb(2), two equivalent Rb(1), one Re(1), one Re(2), and one Re(3) atom. In the fourth S site, S(3) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Re(1), one Re(2), and one Re(3) atom. In the fifth S site, S(4) is bonded in a 4-coordinate geometry to one Rb(2), one Re(1), one Re(2), and one Re(3) atom. In the sixth S site, S(5) is bonded to one Rb(1), one Rb(2), one Re(3), and one S(5) atom to form distorted SRb2ReS tetrahedra that share  a cornercorner with one Re(3)S5 square pyramid. In the seventh S site, S(6) is bonded in a 5-coordinate geometry to one Rb(1), two equivalent Rb(2), one Re(1), and one S(6) atom. is represented by the Crystallographic Information File (CIF) [CIF]
