Title: Materials Data on MgZn5 by Materials Project

Abstract

MgZn5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mg is bonded to twelve Zn atoms to form MgZn12 cuboctahedra that share corners with eighteen equivalent ZnMg3Zn9 cuboctahedra, edges with six equivalent MgZn12 cuboctahedra, edges with twelve equivalent ZnMg2Zn10 cuboctahedra, faces with two equivalent MgZn12 cuboctahedra, and faces with eighteen ZnMg2Zn10 cuboctahedra. There are six shorter (2.77 Å) and six longer (2.90 Å) Mg–Zn bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded to two equivalent Mg and ten Zn atoms to form ZnMg2Zn10 cuboctahedra that share corners with eighteen equivalent ZnMg2Zn10 cuboctahedra, edges with four equivalent MgZn12 cuboctahedra, edges with fourteen ZnMg2Zn10 cuboctahedra, faces with four equivalent MgZn12 cuboctahedra, and faces with sixteen ZnMg2Zn10 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.72–2.87 Å. In the second Zn site, Zn is bonded to three equivalent Mg and nine Zn atoms to form distorted ZnMg3Zn9 cuboctahedra that share corners with nine equivalent MgZn12 cuboctahedra, corners with nine equivalent ZnMg3Zn9 cuboctahedra, edges with eighteen ZnMg2Zn10 cuboctahedra, faces with three equivalent MgZn12 cuboctahedra, and faces with seventeen ZnMg2Zn10 cuboctahedra. All Zn–Zn bond lengths are 2.77 Å.
