AgCuSn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgCuSn2 cluster. Ag(1) is bonded in a distorted single-bond geometry to one Cu(1) atom. The Ag(1)-Cu(1) bond length is 1.74 Å. Cu(1) is bonded in a 2-coordinate geometry to one Ag(1) and one Sn(2) atom. The Cu(1)-Sn(2) bond length is 2.11 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.23 Å. In the second Sn site, Sn(2) is bonded in a distorted linear geometry to one Cu(1) and one Sn(1) atom.
