The structure described by Ag2S is Cotunnite structured and crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to three equivalent S(1) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. S(1) is bonded in a 7-coordinate geometry to three equivalent Ag(1) and four equivalent Ag(2) atoms. is represented by the CIF card [CIF]
