SrCeO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Ce(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles range from 34-36°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1) and two equivalent Ce(1) atoms to form distorted corner-sharing OSr2Ce2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent Ce(1) atoms.
SrCeO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.50 Å) and one longer (2.61 Å) Sr(1)-O(1) bond length. There are a spread of Sr(1)-O(2) bond distances ranging from 2.52-3.09 Å. Ce(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles range from 34-36°. Both Ce(1)-O(1) bond lengths are 2.26 Å. There are two shorter (2.24 Å) and two longer (2.26 Å) Ce(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1) and two equivalent Ce(1) atoms to form distorted corner-sharing OSr2Ce2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent Ce(1) atoms.
