The compound described by MgFePbO3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 3-coordinate geometry to one Pb(1), one O(1), and two equivalent O(2) atoms. Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 4°. Pb(1) is bonded in a 4-coordinate geometry to one Mg(1), one O(1), and two equivalent O(2) atoms. 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), two equivalent Fe(1), and one Pb(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), two equivalent Fe(1), and one Pb(1) atom. is represented by the CIF card [CIF]
