The crystal structure described by RbGaS2 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(3), one S(5), two equivalent S(4), and three equivalent S(2) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to one S(1), one S(2), one S(5), two equivalent S(4), and three equivalent S(3) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one S(2), one S(3), one S(4), and one S(5) atom to form corner-sharing GaS4 tetrahedra. In the second Ga site, Ga(2) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form corner-sharing GaS4 tetrahedra. There are five inequivalent S sites. In the first S site, S(1) is bonded in a distorted water-like geometry to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Ga(2) atoms. In the second S site, S(2) is bonded in a 6-coordinate geometry to one Rb(2), three equivalent Rb(1), one Ga(1), and one Ga(2) atom. In the third S site, S(3) is bonded in a 6-coordinate geometry to one Rb(1), three equivalent Rb(2), one Ga(1), and one Ga(2) atom. In the fourth S site, S(4) is bonded in a distorted water-like geometry to two equivalent Rb(1), two equivalent Rb(2), one Ga(1), and one Ga(2) atom. In the fifth S site, S(5) is bonded in a distorted water-like geometry to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
