Rb(CrS2)2 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(1), two equivalent S(4), and three equivalent S(2) atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. In the second Cr site, Cr(2) is bonded to one S(4), two equivalent S(1), and three equivalent S(3) atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. There are four inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Rb(1), one Cr(1), and two equivalent Cr(2) atoms to form a mixture of distorted corner and edge-sharing SRb2Cr3 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Rb(1) and three equivalent Cr(1) atoms to form a mixture of distorted corner and edge-sharing SRb2Cr3 trigonal bipyramids. In the third S site, S(3) is bonded to two equivalent Rb(1) and three equivalent Cr(2) atoms to form a mixture of distorted corner and edge-sharing SRb2Cr3 square pyramids. In the fourth S site, S(4) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Cr(2), and two equivalent Cr(1) atoms.
