GdAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 24°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Gd(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Al(1) atoms.
GdAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.30 Å) and one longer (2.40 Å) Gd(1)-O(2) bond length. There are a spread of Gd(1)-O(1) bond distances ranging from 2.34-2.62 Å. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 24°. Both Al(1)-O(2) bond lengths are 1.90 Å. There are two shorter (1.90 Å) and two longer (1.91 Å) Al(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Gd(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Al(1) atoms.
