Sm2HfPt crystallizes in the trigonal R3m space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a single-bond geometry to one Pt(1) atom. The Sm(1)-Pt(1) bond length is 2.31 Å. In the second Sm site, Sm(2) is bonded in a distorted linear geometry to one Hf(1) and one Pt(1) atom. The Sm(2)-Hf(1) bond length is 2.31 Å. The Sm(2)-Pt(1) bond length is 2.31 Å. Hf(1) is bonded in a 4-coordinate geometry to one Sm(2) and three equivalent Pt(1) atoms. All Hf(1)-Pt(1) bond lengths are 3.00 Å. Pt(1) is bonded in a distorted linear geometry to one Sm(1), one Sm(2), and three equivalent Hf(1) atoms.
