Materials Data on LaMg3 by Materials Project

Abstract

LaMg3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 10-coordinate geometry to eight equivalent Mg and six equivalent La atoms. All Mg–Mg bond lengths are 3.24 Å. There are two shorter (3.64 Å) and four longer (3.80 Å) Mg–La bond lengths. In the second Mg site, Mg is bonded in a distorted body-centered cubic geometry to four equivalent Mg and four equivalent La atoms. All Mg–La bond lengths are 3.24 Å. La is bonded in a distorted body-centered cubic geometry to fourteen Mg atoms.
