The material described by La2Mn3PbO9 is Orthorhombic Perovskite-derived structured and crystallizes in the trigonal P-3c1 space group. La(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent O(2) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 21°. In the second Mn site, Mn(2) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 14-21°. Pb(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1), two equivalent Mn(2), and one Pb(1) atom to form a mixture of distorted corner and edge-sharing OLa2Mn2Pb square pyramids. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent La(1), one Mn(1), and one Mn(2) atom. is represented by the CIF file [CIF]
