AlO2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. Al(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 55°. O(1) is bonded in a trigonal planar geometry to three equivalent Al(1) atoms.

The corner-sharing octahedral tilt angles are 55°. There are two shorter (1.89 Å) and four longer (1.92 Å) Al(1)-O(1) bond lengths. O(1) is bonded in a trigonal planar geometry to three equivalent Al(1) atoms.
