GaAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ga(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Al(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ga(1) and two equivalent Al(1) atoms to form distorted corner-sharing OAl2Ga2 trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ga(1) and two equivalent Al(1) atoms.
GaAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ga(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There is one shorter (1.97 Å) and one longer (2.02 Å) Ga(1)-O(1) bond length. There are two shorter (1.94 Å) and two longer (2.42 Å) Ga(1)-O(2) bond lengths. Al(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 44°. Both Al(1)-O(1) bond lengths are 2.01 Å. There are two shorter (1.88 Å) and two longer (1.89 Å) Al(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ga(1) and two equivalent Al(1) atoms to form distorted corner-sharing OAl2Ga2 trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ga(1) and two equivalent Al(1) atoms.
