Materials Data on CeMgAu by Materials Project

Abstract

MgCeAu crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mg is bonded in a 4-coordinate geometry to four Au atoms. There are two shorter (2.82 Å) and two longer (2.98 Å) Mg–Au bond lengths. Ce is bonded in a 5-coordinate geometry to five Au atoms. There are four shorter (3.13 Å) and one longer (3.20 Å) Ce–Au bond lengths. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 9-coordinate geometry to three equivalent Mg and six equivalent Ce atoms. In the second Au site, Au is bonded in a 9-coordinate geometry to six equivalent Mg and three equivalent Ce atoms.
