The material structure described by Ag2S crystallizes in the triclinic P1 space group. There are six inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted bent 150 degrees geometry to one S(1) and one S(3) atom. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one S(3) and two equivalent S(1) atoms. In the third Ag site, Ag(3) is bonded in a distorted trigonal planar geometry to one S(2) and two equivalent S(3) atoms. In the fourth Ag site, Ag(4) is bonded in a distorted bent 150 degrees geometry to one S(1) and two equivalent S(2) atoms. In the fifth Ag site, Ag(5) is bonded in a distorted trigonal planar geometry to one S(1) and two equivalent S(2) atoms. In the sixth Ag site, Ag(6) is bonded in a 4-coordinate geometry to two equivalent S(2) and two equivalent S(3) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(4), one Ag(5), and two equivalent Ag(2) atoms. In the second S site, S(2) is bonded in a 7-coordinate geometry to one Ag(3), two equivalent Ag(4), two equivalent Ag(5), and two equivalent Ag(6) atoms. In the third S site, S(3) is bonded in a 6-coordinate geometry to one Ag(1), one Ag(2), two equivalent Ag(3), and two equivalent Ag(6) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
