Ag2Y crystallizes in the triclinic P-1 space group. Y(1) is bonded in a 3-coordinate geometry to two equivalent Ag(2) and four equivalent Ag(1) atoms. There is one shorter (2.22 Å) and one longer (2.36 Å) Y(1)-Ag(2) bond length. There are a spread of Y(1)-Ag(1) bond distances ranging from 2.47-3.53 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to four equivalent Y(1) and two equivalent Ag(2) atoms. There is one shorter (2.35 Å) and one longer (2.45 Å) Ag(1)-Ag(2) bond length. In the second Ag site, Ag(2) is bonded in a distorted water-like geometry to two equivalent Y(1) and two equivalent Ag(1) atoms.
