Sr3Eu is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a body-centered cubic geometry to four equivalent Sr(2) and four equivalent Eu(1) atoms. In the second Sr site, Sr(2) is bonded in a body-centered cubic geometry to eight equivalent Sr(1) atoms. Eu(1) is bonded in a body-centered cubic geometry to eight equivalent Sr(1) atoms.
