MgLaFeO3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. La(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one La(1), and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), one La(1), and two equivalent Fe(1) atoms.
MgLaFeO3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. The Mg(1)-O(2) bond length is 1.97 Å. Both Mg(1)-O(1) bond lengths are 1.97 Å. La(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. The La(1)-O(2) bond length is 2.32 Å. Both La(1)-O(1) bond lengths are 2.33 Å. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There is one shorter (2.17 Å) and one longer (2.34 Å) Fe(1)-O(2) bond length. There are two shorter (2.16 Å) and two longer (2.33 Å) Fe(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one La(1), and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), one La(1), and two equivalent Fe(1) atoms.
