SmRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sm(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 37-38°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sm(1) and two equivalent Rh(1) atoms to form distorted OSm3Rh2 trigonal bipyramids that share corners with nine equivalent O(1)Sm3Rh2 trigonal bipyramids, corners with four equivalent O(2)Sm2Rh2 trigonal pyramids, edges with six equivalent O(1)Sm3Rh2 trigonal bipyramids, and edges with three equivalent O(2)Sm2Rh2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Sm(1) and two equivalent Rh(1) atoms to form distorted OSm2Rh2 trigonal pyramids that share corners with eight equivalent O(1)Sm3Rh2 trigonal bipyramids, corners with four equivalent O(2)Sm2Rh2 trigonal pyramids, and edges with six equivalent O(1)Sm3Rh2 trigonal bipyramids.
SmRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.28 Å) and one longer (2.34 Å) Sm(1)-O(2) bond length. There are a spread of Sm(1)-O(1) bond distances ranging from 2.33-2.68 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 37-38°. Both Rh(1)-O(2) bond lengths are 2.04 Å. There are two shorter (2.07 Å) and two longer (2.08 Å) Rh(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sm(1) and two equivalent Rh(1) atoms to form distorted OSm3Rh2 trigonal bipyramids that share corners with nine equivalent O(1)Sm3Rh2 trigonal bipyramids, corners with four equivalent O(2)Sm2Rh2 trigonal pyramids, edges with six equivalent O(1)Sm3Rh2 trigonal bipyramids, and edges with three equivalent O(2)Sm2Rh2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Sm(1) and two equivalent Rh(1) atoms to form distorted OSm2Rh2 trigonal pyramids that share corners with eight equivalent O(1)Sm3Rh2 trigonal bipyramids, corners with four equivalent O(2)Sm2Rh2 trigonal pyramids, and edges with six equivalent O(1)Sm3Rh2 trigonal bipyramids.
