HoEu2Rh crystallizes in the trigonal R3m space group. Ho(1) is bonded to one Eu(1), one Eu(2), and three equivalent Rh(1) atoms to form corner-sharing HoEu2Rh3 trigonal bipyramids. The Ho(1)-Eu(1) bond length is 1.98 Å. The Ho(1)-Eu(2) bond length is 1.98 Å. All Ho(1)-Rh(1) bond lengths are 3.03 Å. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted linear geometry to one Ho(1) and one Rh(1) atom. The Eu(1)-Rh(1) bond length is 1.98 Å. In the second Eu site, Eu(2) is bonded in a distorted single-bond geometry to one Ho(1) atom. Rh(1) is bonded in a distorted single-bond geometry to three equivalent Ho(1) and one Eu(1) atom.
