The structure described by Al(BiO2)2 crystallizes in the tetragonal P4/ncc space group. Al(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. Bi(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing BiO6 pentagonal pyramids. O(1) is bonded in a 4-coordinate geometry to one Al(1) and three equivalent Bi(1) atoms. is represented by the CIF file [CIF]
