The crystal structure described by Ag2S crystallizes in the monoclinic Cm space group. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one S(1) and one S(2) atom. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent S(2) atoms. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to three equivalent S(1) atoms. In the fourth Ag site, Ag(4) is bonded in a linear geometry to one S(1) and one S(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(4), and three equivalent Ag(3) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(4), and three equivalent Ag(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
