Materials Data on Mg2Zn by Materials Project

Abstract

Mg2Zn crystallizes in the monoclinic C2/c 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 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 2.96–3.13 Å. There are a spread of Mg–Zn bond distances ranging from 2.98–3.05 Å. In the second Mg site, Mg is bonded to seven Mg and five equivalent Zn atoms to form a mixture of distorted face, edge, and corner-sharing MgMg7Zn5 cuboctahedra. There are one shorter (3.02 Å) and one longer (3.10 Å) Mg–Mg bond lengths. There are a spread of Mg–Zn bond distances ranging from 2.98–3.05 Å. Zn is bonded in a 12-coordinate geometry to ten Mg atoms.
