Materials Data on Mg6SnMo by Materials Project
Abstract
Mg6MoSn crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded to eight Mg, two equivalent Mo, and two equivalent Sn atoms to form distorted MgMg8Sn2Mo2 cuboctahedra that share corners with four equivalent MoMg10Sn2 cuboctahedra, corners with four equivalent SnMg10Mo2 cuboctahedra, corners with ten equivalent MgMg8Sn2Mo2 cuboctahedra, edges with two equivalent MoMg10Sn2 cuboctahedra, edges with two equivalent SnMg10Mo2 cuboctahedra, edges with six MgMg8Sn2Mo2 cuboctahedra, faces with two equivalent MoMg10Sn2 cuboctahedra, faces with two equivalent SnMg10Mo2 cuboctahedra, and faces with six MgMg8Sn2Mo2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.97–3.12 Å. There are one shorter (3.09 Å) and one longer (3.11 Å) Mg–Mo bond lengths. Both Mg–Sn bond lengths are 3.10 Å. In the second Mg site, Mg is bonded in a 12-coordinate geometry to eight Mg, two equivalent Mo, and two equivalent Sn atoms. There are a spread of Mg–Mg bond distances ranging from 2.82–3.24 Å. Both Mg–Mo bond lengths are 3.04 Å. Both Mg–Sn bond lengths are 3.12 Å. In the third Mg site, Mg is bonded to ten Mg and two equivalent Sn atoms to form distorted MgMg10Sn2 cuboctahedramore »
