The material described by MgLa2(FeO3)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second La site, La(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and two equivalent O(5) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Fe site, Fe(2) is bonded in a square co-planar geometry to one O(2), one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a see-saw-like geometry to one Mg(1), one La(1), one La(2), and one Fe(1) atom. In the second O site, O(2) is bonded to one Mg(1), one La(1), one La(2), one Fe(1), and one Fe(2) atom to form a mixture of distorted corner and edge-sharing OLa2MgFe2 trigonal bipyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Mg(1), one La(1), one La(2), one Fe(1), and one Fe(2) atom. In the fourth O site, O(4) is bonded to one Mg(1), one La(1), one La(2), one Fe(1), and one Fe(2) atom to form a mixture of distorted corner and edge-sharing OLa2MgFe2 trigonal bipyramids. In the fifth O site, O(5) is bonded in a 6-coordinate geometry to one Mg(1), one La(1), two equivalent La(2), one Fe(1), and one Fe(2) atom. In the sixth O site, O(6) is bonded in a see-saw-like geometry to one Mg(1), one La(1), one La(2), and one Fe(1) atom. is represented by the CIF file [CIF]
