The compound described by Cs2S is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 5-coordinate geometry to five equivalent S(1) atoms. In the second Cs site, Cs(2) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CsS4 tetrahedra. S(1) is bonded in a 9-coordinate geometry to four equivalent Cs(2) and five equivalent Cs(1) atoms. is represented by the CIF card [CIF]
