Title: Materials Data on Mg7Mn by Materials Project

Abstract

Mg7Mn crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Mn atoms to form MgMg10Mn2 cuboctahedra that share corners with four equivalent MnMg12 cuboctahedra, corners with fourteen equivalent MgMg10Mn2 cuboctahedra, edges with two equivalent MnMg12 cuboctahedra, edges with sixteen MgMg10Mn2 cuboctahedra, faces with two equivalent MnMg12 cuboctahedra, and faces with eighteen MgMg10Mn2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.04–3.10 Å. Both Mg–Mn bond lengths are 3.08 Å. In the second Mg site, Mg is bonded to ten Mg and two equivalent Mn atoms to form distorted MgMg10Mn2 cuboctahedra that share corners with eighteen MgMg10Mn2 cuboctahedra, edges with four equivalent MnMg12 cuboctahedra, edges with fourteen MgMg10Mn2 cuboctahedra, faces with two equivalent MnMg12 cuboctahedra, and faces with eighteen MgMg10Mn2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.89–3.27 Å. Both Mg–Mn bond lengths are 2.97 Å. In the third Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with eighteen MgMg10Mn2 cuboctahedra, edges with eighteen MgMg10Mn2 cuboctahedra, faces with six equivalent MnMg12 cuboctahedra, and facesmore » with fourteen MgMg10Mn2 cuboctahedra.
