Materials Data on MgZn2 by Materials Project
MgZn2 is Cubic Laves structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. Mg is bonded in a 12-coordinate geometry to four equivalent Mg and twelve Zn atoms. There are three shorter (3.20 Å) and one longer (3.21 Å) Mg–Mg bond lengths. There are a spread of Mg–Zn bond distances ranging from 3.05–3.08 Å. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded to six equivalent Mg and six equivalent Zn atoms to form a mixture of edge, corner, and face-sharing ZnMg6Zn6 cuboctahedra. All Zn–Zn bond lengths are 2.62 Å. In the second Zn site, Zn is bonded to six equivalent Mg and six Zn atoms to form a mixture of edge, corner, and face-sharing ZnMg6Zn6 cuboctahedra. All Zn–Zn bond lengths are 2.61 Å.
