MgEu3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Mg(1) is bonded in a body-centered cubic geometry to eight equivalent Eu(1) atoms. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mg(1) and four equivalent Eu(2) atoms. In the second Eu site, Eu(2) is bonded in a body-centered cubic geometry to eight equivalent Eu(1) atoms.
