The material structure described by La2O3MgO is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Cmce space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 11°. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and four equivalent La(1) atoms to form a mixture of distorted edge, corner, and face-sharing OLa4Mg2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Mg(1) and four equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
