BaCeO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 9-coordinate geometry to three 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 22-25°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms.
BaCeO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. There are a spread of Ba(1)-O(1) bond distances ranging from 2.72-3.42 Å. There are a spread of Ba(1)-O(2) bond distances ranging from 2.75-3.18 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 22-25°. Both Ce(1)-O(1) bond lengths are 2.25 Å. There are two shorter (2.25 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 in a 4-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms.
