RuAg2Cu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RuAg2Cu cluster. Ru(1) is bonded in a 2-coordinate geometry to one Ag(2) and one Cu(1) atom. The Ru(1)-Ag(2) bond length is 2.21 Å. The Ru(1)-Cu(1) bond length is 2.02 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Ag(2) and one Cu(1) atom. The Ag(1)-Ag(2) bond length is 2.02 Å. The Ag(1)-Cu(1) bond length is 2.21 Å. In the second Ag site, Ag(2) is bonded in a 1-coordinate geometry to one Ru(1) and one Ag(1) atom. Cu(1) is bonded in a 1-coordinate geometry to one Ru(1) and one Ag(1) atom.
