Materials Data on SrMg3O4 by Materials Project
SrMg3O4 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sr–O bond lengths are 2.56 Å. There are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.39 Å) Mg–O bond lengths. In the second Mg2+ site, Mg2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Mg–O bond lengths are 2.39 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a body-centered cubic geometry to four equivalent Sr2+ and four equivalent Mg2+ atoms. In the second O2- site, O2- is bonded in a body-centered cubic geometry to eight Mg2+ atoms.
