Materials Data on Eu3Sn13Rh4 by Materials Project

SnEu3Rh4Sn12 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to four equivalent Rh and twelve equivalent Sn atoms. All Eu–Rh bond lengths are 3.49 Å. There are four shorter (3.46 Å) and eight longer (3.49 Å) Eu–Sn bond lengths. Rh is bonded in a 6-coordinate geometry to three equivalent Eu and six equivalent Sn atoms. All Rh–Sn bond lengths are 2.70 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to three equivalent Eu, two equivalent Rh, 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.
