The material described by AlO3 is alpha Rhenium trioxide-like structured and crystallizes in the trigonal R-3c space group. Al(1) is bonded to six equivalent O(1) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 9°. O(1) is bonded in a linear geometry to two equivalent Al(1) atoms. is represented by the CIF card [CIF]
