AgCu3(AgCu)2 is Cubic alpha N2-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgCu cluster and one AgCu3 cluster. In the AgCu cluster, there are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one Ag(2), one Cu(2), and one Cu(3) atom. The Ag(1)-Ag(2) bond length is 1.16 Å. The Ag(1)-Cu(2) bond length is 0.74 Å. The Ag(1)-Cu(3) bond length is 1.16 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Ag(1), one Cu(2), and one Cu(3) atom. The Ag(2)-Cu(2) bond length is 1.16 Å. The Ag(2)-Cu(3) bond length is 0.74 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one Cu(3) atom. The Cu(2)-Cu(3) bond length is 1.16 Å. In the second Cu site, Cu(3) is bonded in a single-bond geometry to one Ag(1), one Ag(2), and one Cu(2) atom. In the AgCu3 cluster, Ag(3) is bonded in a single-bond geometry to one Cu(4) and two equivalent Cu(1,5) atoms. The Ag(3)-Cu(4) bond length is 0.74 Å. Both Ag(3)-Cu(1,5) bond lengths are 1.16 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1,5) is bonded in a 3-coordinate geometry to one Ag(3); one Cu(1,5); and one Cu(4) atom. The Cu(1,5)-Cu(1,5) bond length is 0.74 Å. The Cu(1,5)-Cu(4) bond length is 1.16 Å. In the second Cu site, Cu(4) is bonded in a single-bond geometry to one Ag(3) and two equivalent Cu(1,5) atoms.
