The structure described by RbInS2 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 6-coordinate geometry to one S(2), one S(3), one S(4), one S(5), and two equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to one S(2), one S(3), one S(4), one S(5), and two equivalent S(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to one S(1), one S(3), one S(4), and one S(5) atom to form corner-sharing InS4 tetrahedra. In the second In site, In(2) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form corner-sharing InS4 tetrahedra. There are five inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one In(1), and one In(2) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and two equivalent In(2) atoms. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to one Rb(1), one Rb(2), one In(1), and one In(2) atom. In the fourth S site, S(4) is bonded in a distorted rectangular see-saw-like geometry to one Rb(1), one Rb(2), one In(1), and one In(2) atom. In the fifth S site, S(5) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and two equivalent In(1) atoms. is represented by the CIF file [CIF]
