Sm Ru Ru Rh
SmRu2Rh crystallizes in the trigonal R3m space group. Sm(1) is bonded in a 10-coordinate geometry to three equivalent Ru(1), three equivalent Ru(2), and four equivalent Rh(1) atoms. All Sm(1)-Ru(1) bond lengths are 2.70 Å. All Sm(1)-Ru(2) bond lengths are 2.70 Å. There is one shorter (2.73 Å) and three longer (2.84 Å) Sm(1)-Rh(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to three equivalent Sm(1) and one Rh(1) atom. The Ru(1)-Rh(1) bond length is 1.53 Å. In the second Ru site, Ru(2) is bonded in a 3-coordinate geometry to three equivalent Sm(1) atoms. Rh(1) is bonded in a 2-coordinate geometry to four equivalent Sm(1) and one Ru(1) atom.
