Rb(CrS2)2 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to two equivalent S(2) and four equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent S(3) and four equivalent S(1) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(2), one S(3), and four equivalent S(1) atoms to form edge-sharing CrS6 octahedra. In the second Cr site, Cr(2) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form edge-sharing CrS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Rb(1), one Rb(2), one Cr(2), and two equivalent Cr(1) atoms to form a mixture of distorted edge and corner-sharing SRb2Cr3 trigonal bipyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Rb(1), one Cr(1), and two equivalent Cr(2) atoms. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to one Rb(2), one Cr(1), and two equivalent Cr(2) atoms.
