The material structure described by BaMgEuFe2O5 crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. Mg(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. Eu(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Fe(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ba(1), one Mg(1), one Eu(1), and one Fe(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent Ba(1) and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
