Fe Co Co Rh
FeRhCo2 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one FeRhCo2 cluster. Fe(1) is bonded in an L-shaped geometry to one Rh(1) and one Co(2) atom. The Fe(1)-Rh(1) bond length is 0.76 Å. The Fe(1)-Co(2) bond length is 0.76 Å. Rh(1) is bonded in a single-bond geometry to one Fe(1) and one Co(1) atom. The Rh(1)-Co(1) bond length is 1.71 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. In the second Co site, Co(2) is bonded in a distorted single-bond geometry to one Fe(1) atom.
