BiRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 37-40°. Bi(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Rh(1) and three equivalent Bi(1) atoms. In the second O site, O(2) is bonded to two equivalent Rh(1) and two equivalent Bi(1) atoms to form distorted corner-sharing OBi2Rh2 trigonal pyramids.
BiRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 37-40°. Both Rh(1)-O(2) bond lengths are 2.08 Å. There are two shorter (2.11 Å) and two longer (2.12 Å) Rh(1)-O(1) bond lengths. Bi(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.26 Å) and one longer (2.41 Å) Bi(1)-O(2) bond length. There are a spread of Bi(1)-O(1) bond distances ranging from 2.35-2.73 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Rh(1) and three equivalent Bi(1) atoms. In the second O site, O(2) is bonded to two equivalent Rh(1) and two equivalent Bi(1) atoms to form distorted corner-sharing OBi2Rh2 trigonal pyramids.
