Ag2Te is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2Te clusters. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one Ag(2) and one Te(1) atom. The Ag(1)-Ag(2) bond length is 0.94 Å. The Ag(1)-Te(1) bond length is 0.73 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Ag(1) atom. Te(1) is bonded in a single-bond geometry to one Ag(1) atom.
