RhCuZn2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RhCuZn2 cluster. Rh(1) is bonded in a single-bond geometry to one Zn(1) atom. The Rh(1)-Zn(1) bond length is 0.85 Å. Cu(1) is bonded in a 2-coordinate geometry to one Zn(1) and one Zn(2) atom. The Cu(1)-Zn(1) bond length is 0.60 Å. The Cu(1)-Zn(2) bond length is 0.77 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate geometry to one Rh(1), one Cu(1), and one Zn(2) atom. The Zn(1)-Zn(2) bond length is 0.75 Å. In the second Zn site, Zn(2) is bonded in a 2-coordinate geometry to one Cu(1) and one Zn(1) atom.
