YbEr2Rh crystallizes in the trigonal R3m space group. Yb(1) is bonded in a 5-coordinate geometry to one Er(1), one Er(2), and three equivalent Rh(1) atoms. The Yb(1)-Er(1) bond length is 2.49 Å. The Yb(1)-Er(2) bond length is 2.49 Å. All Yb(1)-Rh(1) bond lengths are 3.05 Å. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded to one Yb(1) and three equivalent Rh(1) atoms to form distorted corner-sharing ErYbRh3 tetrahedra. All Er(1)-Rh(1) bond lengths are 3.06 Å. In the second Er site, Er(2) is bonded in a 2-coordinate geometry to one Yb(1) and four equivalent Rh(1) atoms. There is one shorter (2.49 Å) and three longer (3.38 Å) Er(2)-Rh(1) bond lengths. Rh(1) is bonded in a 10-coordinate geometry to three equivalent Yb(1), three equivalent Er(1), and four equivalent Er(2) atoms.
