The 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 two equivalent S(1,2) atoms. In the second Ag site, Ag(2) is bonded in a distorted trigonal planar geometry to three equivalent S(1,2) atoms. In the third Ag site, Ag(3) is bonded in a distorted trigonal planar geometry to three equivalent S(1,2) atoms. In the fourth Ag site, Ag(4) is bonded in a linear geometry to two equivalent S(1,2) atoms. S(1,2) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(4), and three equivalent Ag(3) atoms. is represented by the CIF file [CIF]
