RbEu3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded in a body-centered cubic geometry to six equivalent Eu(2) and 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 Rb(1) and four equivalent Eu(2) atoms. In the second Eu site, Eu(2) is bonded in a distorted body-centered cubic geometry to six equivalent Rb(1) and eight equivalent Eu(1) atoms.
