The crystal structure described by SrMg3O4 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Mg site, Mg(2) is bonded in a body-centered cubic geometry to eight equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a body-centered cubic geometry to four equivalent Sr(1) and four equivalent Mg(1) atoms. In the second O site, O(2) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
