Sm5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. In the second Sm site, Sm(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing SmRu4 tetrahedra. In the third Sm site, Sm(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Sm(3), three equivalent Sm(1), and three equivalent Sm(2) atoms.
Sm5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Sm(1)-Ru(1) bond distances ranging from 2.74-3.50 Å. In the second Sm site, Sm(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing SmRu4 tetrahedra. There are two shorter (2.94 Å) and two longer (3.01 Å) Sm(3)-Ru(1) bond lengths. In the third Sm site, Sm(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Sm(2)-Ru(1) bond distances ranging from 2.85-3.14 Å. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Sm(3), three equivalent Sm(1), and three equivalent Sm(2) atoms.
