FeRhP2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeRhP2 clusters. Fe(1) is bonded in a 1-coordinate geometry to one Rh(1) and one P(2) atom. The Fe(1)-Rh(1) bond length is 1.55 Å. The Fe(1)-P(2) bond length is 2.70 Å. Rh(1) is bonded in a 1-coordinate geometry to one Fe(1) and one P(1) atom. The Rh(1)-P(1) bond length is 0.83 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Rh(1) atom. In the second P site, P(2) is bonded in a distorted single-bond geometry to one Fe(1) atom.
