CeRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. 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 40-45°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ce(1) and two equivalent Rh(1) atoms to form distorted OCe3Rh2 trigonal bipyramids that share corners with nine equivalent O(1)Ce3Rh2 trigonal bipyramids, corners with four equivalent O(2)Ce2Rh2 trigonal pyramids, edges with six equivalent O(1)Ce3Rh2 trigonal bipyramids, and edges with three equivalent O(2)Ce2Rh2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Ce(1) and two equivalent Rh(1) atoms to form distorted OCe2Rh2 trigonal pyramids that share corners with eight equivalent O(1)Ce3Rh2 trigonal bipyramids, corners with four equivalent O(2)Ce2Rh2 trigonal pyramids, and edges with six equivalent O(1)Ce3Rh2 trigonal bipyramids.
CeRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.29 Å) and one longer (2.36 Å) Ce(1)-O(2) bond length. There are a spread of Ce(1)-O(1) bond distances ranging from 2.33-2.74 Å. 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 40-45°. Both Rh(1)-O(2) bond lengths are 2.09 Å. All Rh(1)-O(1) bond lengths are 2.15 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ce(1) and two equivalent Rh(1) atoms to form distorted OCe3Rh2 trigonal bipyramids that share corners with nine equivalent O(1)Ce3Rh2 trigonal bipyramids, corners with four equivalent O(2)Ce2Rh2 trigonal pyramids, edges with six equivalent O(1)Ce3Rh2 trigonal bipyramids, and edges with three equivalent O(2)Ce2Rh2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Ce(1) and two equivalent Rh(1) atoms to form distorted OCe2Rh2 trigonal pyramids that share corners with eight equivalent O(1)Ce3Rh2 trigonal bipyramids, corners with four equivalent O(2)Ce2Rh2 trigonal pyramids, and edges with six equivalent O(1)Ce3Rh2 trigonal bipyramids.
