Ag2Y is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ag2Y cluster. Y(1) is bonded in a 1-coordinate geometry to one Ag(1) and one Ag(2) atom. The Y(1)-Ag(1) bond length is 1.55 Å. The Y(1)-Ag(2) bond length is 2.11 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Y(1) atom. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Y(1) atom.
