Ba3Eu is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ba(2) and four equivalent Eu(1) atoms. In the second Ba site, Ba(2) is bonded in a body-centered cubic geometry to eight equivalent Ba(1) atoms. Eu(1) is bonded in a body-centered cubic geometry to eight equivalent Ba(1) atoms.
