Materials Data on La3Sn13Ru4 by Materials Project
La3Ru4Sn13 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. La is bonded in a 12-coordinate geometry to four equivalent Ru and twelve equivalent Sn atoms. All La–Ru bond lengths are 3.49 Å. There are four shorter (3.45 Å) and eight longer (3.50 Å) La–Sn bond lengths. Ru is bonded in a 6-coordinate geometry to three equivalent La and six equivalent Sn atoms. All Ru–Sn bond lengths are 2.69 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to three equivalent La, two equivalent Ru, and one Sn atom. The Sn–Sn bond length is 3.35 Å. In the second Sn site, Sn is bonded in a cuboctahedral geometry to twelve equivalent Sn atoms.
