The structure described by AlO3 crystallizes in the monoclinic C2 space group. Al(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to two equivalent Al(1) and one O(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one O(1) and one O(2) atom. In the third O site, O(3) is bonded to four equivalent Al(1) atoms to form a mixture of corner and edge-sharing OAl4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
