The compound described by Ca2BeEuO5 crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and three equivalent O(4) atoms. Be(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(4) atoms. Eu(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(1), and four equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Ca(1) and two equivalent Eu(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Ca(1), one Be(1), and one Eu(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to four equivalent Ca(1), one Be(1), and one Eu(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to three equivalent Ca(1), one Be(1), and two equivalent Eu(1) atoms. is represented by the CIF file [CIF]
