Materials Data on Sm5Ru2 by Materials Project
Sm5Ru2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Sm sites. In the first Sm site, Sm is bonded in a 2-coordinate geometry to three equivalent Ru atoms. There are a spread of Sm–Ru bond distances ranging from 2.80–3.48 Å. In the second Sm site, Sm is bonded to four equivalent Ru atoms to form distorted edge-sharing SmRu4 tetrahedra. There are two shorter (2.95 Å) and two longer (3.00 Å) Sm–Ru bond lengths. In the third Sm site, Sm is bonded in a 3-coordinate geometry to three equivalent Ru atoms. There are a spread of Sm–Ru bond distances ranging from 2.87–3.13 Å. Ru is bonded in a 7-coordinate geometry to eight Sm atoms.
