Ag3Cd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ag3Cd cluster. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 1-coordinate geometry to one Ag(3) atom. The Ag(1)-Ag(3) bond length is 1.56 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Cd(1) atom. The Ag(2)-Cd(1) bond length is 1.45 Å. In the third Ag site, Ag(3) is bonded in a 2-coordinate geometry to one Ag(1) and one Cd(1) atom. The Ag(3)-Cd(1) bond length is 1.93 Å. Cd(1) is bonded in a 2-coordinate geometry to one Ag(2) and one Ag(3) atom.
