The material structure described by AlO2 crystallizes in the orthorhombic Pnma space group. Al(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to three equivalent Al(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Al(1) atoms. is represented by the CIF file [CIF]
