Ag2S crystallizes in the triclinic P1 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.
Ag2S crystallizes in the triclinic P1 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. The Ag(1)-S(1) bond length is 2.44 Å. The Ag(1)-S(2) bond length is 2.44 Å. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent S(2) atoms. There are two shorter (2.51 Å) and one longer (2.77 Å) Ag(2)-S(2) bond length. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to three equivalent S(1) atoms. There are two shorter (2.51 Å) and one longer (2.75 Å) Ag(3)-S(1) bond length. In the fourth Ag site, Ag(4) is bonded in a linear geometry to one S(1) and one S(2) atom. The Ag(4)-S(1) bond length is 2.42 Å. The Ag(4)-S(2) bond length is 2.43 Å. There are two inequivalent S sites.
