TbRhPt2 crystallizes in the trigonal R3m space group. Tb(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), three equivalent Pt(1), and three equivalent Pt(2) atoms. There are three shorter (2.77 Å) and one longer (3.02 Å) Tb(1)-Rh(1) bond length. All Tb(1)-Pt(1) bond lengths are 2.69 Å. All Tb(1)-Pt(2) bond lengths are 2.69 Å. Rh(1) is bonded in a distorted single-bond geometry to four equivalent Tb(1) and one Pt(1) atom. The Rh(1)-Pt(1) bond length is 1.12 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to three equivalent Tb(1) and one Rh(1) atom. In the second Pt site, Pt(2) is bonded in a distorted trigonal planar geometry to three equivalent Tb(1) atoms.
