Title: Materials Data on Sm6Fe13Sn by Materials Project

Abstract

Sm6Fe13Sn crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 1-coordinate geometry to twelve Fe and one Sn atom. There are a spread of Sm–Fe bond distances ranging from 3.01–3.25 Å. The Sm–Sn bond length is 3.35 Å. In the second Sm site, Sm is bonded in a 6-coordinate geometry to four Fe and two equivalent Sn atoms. There are a spread of Sm–Fe bond distances ranging from 2.92–3.30 Å. Both Sm–Sn bond lengths are 3.36 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a 12-coordinate geometry to three Sm and nine Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.46–2.76 Å. In the second Fe site, Fe is bonded to five Sm and seven Fe atoms to form a mixture of distorted corner and face-sharing FeSm5Fe7 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.55–2.65 Å. In the third Fe site, Fe is bonded to twelve Fe atoms to form FeFe12 cuboctahedra that share corners with eight FeSm2Fe10 cuboctahedra and faces with twelve FeSm5Fe7 cuboctahedra. Allmore » Fe–Fe bond lengths are 2.40 Å. In the fourth Fe site, Fe is bonded to two equivalent Sm and ten Fe atoms to form a mixture of corner and face-sharing FeSm2Fe10 cuboctahedra. There are two shorter (2.50 Å) and one longer (2.56 Å) Fe–Fe bond lengths. Sn is bonded in a distorted q6 geometry to ten Sm atoms.« less
