ZrRh2Co is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrRh2Co clusters. Zr(1) is bonded in a 3-coordinate geometry to two equivalent Rh(1) and one Co(1) atom. Both Zr(1)-Rh(1) bond lengths are 0.31 Å. The Zr(1)-Co(1) bond length is 0.18 Å. Rh(1) is bonded in a 3-coordinate geometry to one Zr(1), one Rh(1), and one Co(1) atom. The Rh(1)-Rh(1) bond length is 0.18 Å. The Rh(1)-Co(1) bond length is 0.31 Å. Co(1) is bonded in a distorted single-bond geometry to one Zr(1) and two equivalent Rh(1) atoms.
