Cs2CoS2 crystallizes in the orthorhombic Ibam space group. Cs(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 Cs(1) and four equivalent S(1) atoms to form distorted face-sharing CoCs4S4 tetrahedra. S(1) is bonded in a 2-coordinate geometry to six equivalent Cs(1) and two equivalent Co(1) atoms.
Cs2CoS2 crystallizes in the orthorhombic Ibam space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Co(1) and six equivalent S(1) atoms. Both Cs(1)-Co(1) bond lengths are 3.56 Å.
