The structure described by MgLa4MnO8 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to two equivalent O(2), three equivalent O(3), and four equivalent O(1) atoms. In the second La site, La(2) is bonded in a 5-coordinate geometry to two equivalent O(3) and three equivalent O(2) atoms. Mn(1) is bonded in a distorted octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted L-shaped geometry to one Mg(1), two equivalent La(1), and one Mn(1) atom. In the second O site, O(2) is bonded to two equivalent La(1), three equivalent La(2), and one Mn(1) atom to form distorted OLa5Mn octahedra that share corners with five equivalent O(2)La5Mn octahedra, edges with two equivalent O(2)La5Mn octahedra, and edges with six equivalent O(3)La5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-30°. In the third O site, O(3) is bonded to two equivalent La(2) and three equivalent La(1) atoms to form OLa5 trigonal bipyramids that share corners with four equivalent O(3)La5 trigonal bipyramids, edges with six equivalent O(2)La5Mn octahedra, and edges with two equivalent O(3)La5 trigonal bipyramids. is represented by the CIF card [CIF]
