Rb2CoS2 crystallizes in the orthorhombic Ibam space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Co(1) and six equivalent S(1) atoms. Co(1) is bonded to four equivalent Rb(1) and four equivalent S(1) atoms to form distorted face-sharing CoRb4S4 tetrahedra. S(1) is bonded in a 8-coordinate geometry to six equivalent Rb(1) and two equivalent Co(1) atoms.
Rb2CoS2 crystallizes in the orthorhombic Ibam space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Co(1) and six equivalent S(1) atoms. Both Rb(1)-Co(1) bond lengths are 3.42 Å. There are a spread of Rb(1)-S(1) bond distances ranging from 3.33-3.64 Å. Co(1) is bonded to four equivalent Rb(1) and four equivalent S(1) atoms to form distorted face-sharing CoRb4S4 tetrahedra. All Co(1)-S(1) bond lengths are 2.32 Å. S(1) is bonded in a 8-coordinate geometry to six equivalent Rb(1) and two equivalent Co(1) atoms.
