The compound described by BeEu3O5 crystallizes in the orthorhombic Pnma space group. Be(1) is bonded in a tetrahedral geometry to one O(1), one O(4), and two equivalent O(2) atoms. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 8-coordinate geometry to one O(1), one O(4), two equivalent O(3), and four equivalent O(2) atoms. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and three equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Be(1), one Eu(1), and four equivalent Eu(2) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to one Be(1), two equivalent Eu(1), and three equivalent Eu(2) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Eu(1) and four equivalent Eu(2) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Be(1), one Eu(1), and four equivalent Eu(2) atoms. is represented by the CIF file [CIF]
