Sm2PrPd crystallizes in the trigonal R3m space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a distorted single-bond geometry to one Pr(1) atom. The Sm(1)-Pr(1) bond length is 1.70 Å. In the second Sm site, Sm(2) is bonded in a distorted linear geometry to one Pr(1) and one Pd(1) atom. The Sm(2)-Pr(1) bond length is 1.70 Å. The Sm(2)-Pd(1) bond length is 1.70 Å. Pr(1) is bonded in a 5-coordinate geometry to one Sm(1), one Sm(2), and three equivalent Pd(1) atoms. All Pr(1)-Pd(1) bond lengths are 3.18 Å. Pd(1) is bonded in a single-bond geometry to one Sm(2) and three equivalent Pr(1) atoms.
