Zr2Rh crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Zr2Rh clusters. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a single-bond geometry to one Zr(2) and one Rh(1) atom. The Zr(1)-Zr(2) bond length is 1.64 Å. The Zr(1)-Rh(1) bond length is 0.37 Å. In the second Zr site, Zr(2) is bonded in a distorted single-bond geometry to one Zr(1) atom. Rh(1) is bonded in a single-bond geometry to one Zr(1) atom.
