Title: Materials Data on Mg6FeSn by Materials Project

Abstract

Mg6FeSn crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are seven inequivalent Mg sites. In the first Mg site, Mg is bonded to eight Mg, two equivalent Fe, and two equivalent Sn atoms to form distorted MgMg8Fe2Sn2 cuboctahedra that share corners with four equivalent FeMg10Sn2 cuboctahedra, corners with four equivalent SnMg10Fe2 cuboctahedra, corners with ten MgMg8Fe2Sn2 cuboctahedra, edges with two equivalent FeMg10Sn2 cuboctahedra, edges with two equivalent SnMg10Fe2 cuboctahedra, edges with ten MgMg8Fe2Sn2 cuboctahedra, faces with two equivalent FeMg10Sn2 cuboctahedra, faces with two equivalent SnMg10Fe2 cuboctahedra, and faces with fourteen MgMg8Fe2Sn2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.06–3.13 Å. There are one shorter (3.12 Å) and one longer (3.13 Å) Mg–Fe bond lengths. There are one shorter (3.11 Å) and one longer (3.13 Å) Mg–Sn bond lengths. In the second Mg site, Mg is bonded to eight Mg, two equivalent Fe, and two equivalent Sn atoms to form distorted MgMg8Fe2Sn2 cuboctahedra that share corners with four equivalent FeMg10Sn2 cuboctahedra, corners with four equivalent SnMg10Fe2 cuboctahedra, corners with ten MgMg8Fe2Sn2 cuboctahedra, edges with two equivalent FeMg10Sn2 cuboctahedra, edges with two equivalent SnMg10Fe2 cuboctahedra, edges with ten MgMg8Fe2Sn2 cuboctahedra, faces with two equivalentmore » FeMg10Sn2 cuboctahedra, faces with two equivalent SnMg10Fe2 cuboctahedra, and faces with fourteen MgMg8Fe2Sn2 cuboctahedra.
