Title: Materials Data on Mg2Zn by Materials Project

Abstract

Mg2Zn crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded to nine Mg and three Zn atoms to form distorted MgMg9Zn3 cuboctahedra that share corners with eighteen MgMg9Zn3 cuboctahedra, edges with eight MgMg7Zn5 cuboctahedra, and faces with thirteen MgMg9Zn3 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.97–3.13 Å. There are two shorter (2.92 Å) and one longer (3.02 Å) Mg–Zn bond lengths. In the second Mg site, Mg is bonded to seven Mg and five Zn atoms to form a mixture of distorted face, edge, and corner-sharing MgMg7Zn5 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.02–3.13 Å. There are a spread of Mg–Zn bond distances ranging from 2.90–3.03 Å. In the third Mg site, Mg is bonded to eight Mg and four Zn atoms to form a mixture of distorted face, edge, and corner-sharing MgMg8Zn4 cuboctahedra. There are two shorter (3.06 Å) and two longer (3.13 Å) Mg–Mg bond lengths. There are a spread of Mg–Zn bond distances ranging from 2.82–3.09 Å. In the fourth Mg site, Mg is bonded to eight Mg and four Znmore » atoms to form distorted MgMg8Zn4 cuboctahedra that share corners with six equivalent MgMg8Zn4 cuboctahedra, edges with twelve MgMg9Zn3 cuboctahedra, and faces with fourteen MgMg9Zn3 cuboctahedra. Both Mg–Mg bond lengths are 3.13 Å. There are two shorter (3.06 Å) and two longer (3.14 Å) Mg–Zn bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded in a 12-coordinate geometry to eight Mg atoms. In the second Zn site, Zn is bonded in a 12-coordinate geometry to eight Mg atoms.« less
