AgCu2Sn crystallizes in the triclinic P1 space group. Ag(1) is bonded in a 2-coordinate geometry to one Cu(1), three equivalent Cu(2), and one Sn(1) atom. The Ag(1)-Cu(1) bond length is 2.70 Å. There are a spread of Ag(1)-Cu(2) bond distances ranging from 2.12-3.12 Å. The Ag(1)-Sn(1) bond length is 2.14 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 5-coordinate geometry to one Ag(1), two equivalent Cu(2), and two equivalent Sn(1) atoms. There is one shorter (2.31 Å) and one longer (2.65 Å) Cu(1)-Cu(2) bond length. There is one shorter (2.50 Å) and one longer (2.75 Å) Cu(1)-Sn(1) bond length. In the second Cu site, Cu(2) is bonded in a 10-coordinate geometry to three equivalent Ag(1), two equivalent Cu(1), two equivalent Cu(2), and three equivalent Sn(1) atoms. Both Cu(2)-Cu(2) bond lengths are 3.07 Å. There are a spread of Cu(2)-Sn(1) bond distances ranging from 2.50-3.29 Å. Sn(1) is bonded in a 3-coordinate geometry to one Ag(1), two equivalent Cu(1), and three equivalent Cu(2) atoms.
