ZrRh2Cu is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrRh2Cu clusters. Zr(1) is bonded in a 3-coordinate geometry to two equivalent Rh(1) and one Cu(1) atom. Both Zr(1)-Rh(1) bond lengths are 1.38 Å. The Zr(1)-Cu(1) bond length is 1.24 Å. Rh(1) is bonded in a 2-coordinate geometry to one Zr(1) and one Rh(1) atom. The Rh(1)-Rh(1) bond length is 0.96 Å. Cu(1) is bonded in a distorted single-bond geometry to one Zr(1) atom.
