Cu Cu Ag Rh
RhAgCu2 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a distorted single-bond geometry to one Ag(1), one Cu(1), and two equivalent Cu(2) atoms. The Rh(1)-Ag(1) bond length is 0.65 Å. The Rh(1)-Cu(1) bond length is 2.22 Å. There is one shorter (2.55 Å) and one longer (2.90 Å) Rh(1)-Cu(2) bond length. Ag(1) is bonded in a single-bond geometry to one Rh(1) and two equivalent Cu(2) atoms. There is one shorter (2.22 Å) and one longer (2.62 Å) Ag(1)-Cu(2) bond length. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 2-coordinate geometry to one Rh(1) and two equivalent Cu(2) atoms. There is one shorter (1.68 Å) and one longer (2.94 Å) Cu(1)-Cu(2) bond length. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to two equivalent Rh(1), two equivalent Ag(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. Both Cu(2)-Cu(2) bond lengths are 2.74 Å.
