BiCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 28-29°. Bi(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Cr(1) and two equivalent Bi(1) atoms to form distorted corner-sharing OCr2Bi2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Cr(1) and three equivalent Bi(1) atoms.
BiCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 28-29°. Both Cr(1)-O(1) bond lengths are 1.99 Å. All Cr(1)-O(2) bond lengths are 2.00 Å. Bi(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.31 Å) and one longer (2.42 Å) Bi(1)-O(1) bond length. There are a spread of Bi(1)-O(2) bond distances ranging from 2.38-2.66 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Cr(1) and two equivalent Bi(1) atoms to form distorted corner-sharing OCr2Bi2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Cr(1) and three equivalent Bi(1) atoms.
