The compound described by Ag2S crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent S(1) atoms. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent S(1) atoms. S(1) is bonded in a 5-coordinate geometry to two equivalent Ag(1) and three equivalent Ag(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
