The structure described by MgPr3Al2 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. Mg(1) is bonded in a body-centered cubic geometry to eight equivalent Pr(1) atoms. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mg(1) and four equivalent Al(1) atoms. In the second Pr site, Pr(2) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. Al(1) is bonded in a body-centered cubic geometry to four equivalent Pr(1) and four equivalent Pr(2) atoms. is represented by the CIF file [CIF]
