The structure described by LaCrO3 crystallizes in the trigonal R-3c space group. La(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. Cr(1) is bonded to six equivalent O(1) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 21°. O(1) is bonded in a 3-coordinate geometry to three equivalent La(1) and two equivalent Cr(1) atoms. is represented by the CIF file [CIF]
