The material described by LaCu3Mn4O12 crystallizes in the cubic Im-3 space group. La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share faces with eight equivalent Mn(1)O6 octahedra. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and faces with two equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 43°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to one La(1), two equivalent Mn(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
