Title: Materials Data on Mg2Sc by Materials Project

Abstract

Mg2Sc is Magnesium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to seven Mg and five equivalent Sc atoms to form MgMg7Sc5 cuboctahedra that share corners with six equivalent ScMg9Sc3 cuboctahedra, corners with twelve MgMg8Sc4 cuboctahedra, edges with five equivalent ScMg9Sc3 cuboctahedra, edges with thirteen MgMg7Sc5 cuboctahedra, faces with eight equivalent ScMg9Sc3 cuboctahedra, and faces with twelve MgMg8Sc4 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.14–3.21 Å. There are a spread of Mg–Sc bond distances ranging from 3.22–3.29 Å. In the second Mg site, Mg is bonded to eight Mg and four equivalent Sc atoms to form MgMg8Sc4 cuboctahedra that share corners with six equivalent ScMg9Sc3 cuboctahedra, corners with twelve MgMg7Sc5 cuboctahedra, edges with nine MgMg7Sc5 cuboctahedra, edges with nine equivalent ScMg9Sc3 cuboctahedra, faces with six equivalent ScMg9Sc3 cuboctahedra, and faces with fourteen MgMg7Sc5 cuboctahedra. There are four shorter (3.21 Å) and one longer (3.32 Å) Mg–Mg bond lengths. There are two shorter (3.20 Å) and two longer (3.21 Å) Mg–Sc bond lengths.
