Cr3O is Upper Bainite-like structured and crystallizes in the trigonal R-3c space group. Cr(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. O(1) is bonded to six equivalent Cr(1) atoms to form corner-sharing OCr6 octahedra. The corner-sharing octahedral tilt angles are 48°.
Cr3O is Upper Bainite-like structured and crystallizes in the trigonal R-3c space group. Cr(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. Both Cr(1)-O(1) bond lengths are 2.16 Å. O(1) is bonded to six equivalent Cr(1) atoms to form corner-sharing OCr6 octahedra. The corner-sharing octahedral tilt angles are 48°.
