The material structure described by BiCrO3 crystallizes in the trigonal R3c space group. Cr(1) is bonded to six equivalent O(1) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 24°. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Cr(1) and two equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
