The crystal structure described by LaCr4Mn3O12 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 Cr(1)O6 octahedra. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and faces with two equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 42°. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to one La(1), two equivalent Cr(1), and one Mn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
