The material structure described by MgLa4FeO8 is (La,Ba)CuO4-derived structured and crystallizes in the orthorhombic Cmmm space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to two equivalent O(2), three equivalent O(3), and four equivalent O(1) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(2), and four equivalent O(1) atoms. Fe(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with four equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), two equivalent La(1), two equivalent La(2), and one Fe(1) atom to form a mixture of distorted edge, corner, and face-sharing OLa4MgFe octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 6-coordinate geometry to one Mg(1), two equivalent La(1), and three equivalent La(2) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent La(2), three equivalent La(1), and one Fe(1) atom. is represented by the CIF file [CIF]
