Materials Data on SmSn3Ru by Materials Project
SmRuSn3 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to four equivalent Ru and twelve equivalent Sn atoms. All Sm–Ru bond lengths are 3.46 Å. All Sm–Sn bond lengths are 3.42 Å. In the second Sm site, Sm is bonded in a cuboctahedral geometry to twelve equivalent Sn atoms. All Sm–Sn bond lengths are 3.42 Å. Ru is bonded in a 6-coordinate geometry to three equivalent Sm and six equivalent Sn atoms. All Ru–Sn bond lengths are 2.69 Å. Sn is bonded in a 2-coordinate geometry to four Sm, two equivalent Ru, and three equivalent Sn atoms. There are one shorter (3.05 Å) and two longer (3.18 Å) Sn–Sn bond lengths.
