HfRhP2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfRhP2 clusters. Hf(1) is bonded in a linear geometry to one Rh(1) and one P(1) atom. The Hf(1)-Rh(1) bond length is 0.12 Å. The Hf(1)-P(1) bond length is 0.78 Å. Rh(1) is bonded in a distorted linear geometry to one Hf(1) and one P(2) atom. The Rh(1)-P(2) bond length is 0.66 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Hf(1) atom. In the second P site, P(2) is bonded in a single-bond geometry to one Rh(1) atom.
