Ag2Se crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to three equivalent Se(1) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent Se(1) atoms. Se(1) is bonded in a 7-coordinate geometry to three equivalent Ag(1) and four equivalent Ag(2) atoms.
Ag2Se crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to three equivalent Se(1) atoms. There are a spread of Ag(1)-Se(1) bond distances ranging from 2.68-3.07 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent Se(1) atoms. There are a spread of Ag(2)-Se(1) bond distances ranging from 2.62-3.12 Å. Se(1) is bonded in a 7-coordinate geometry to three equivalent Ag(1) and four equivalent Ag(2) atoms.
