The material structure described by Al(WO2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second W site, W(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing AlO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one W(1), one W(2), and two equivalent Al(1) atoms to form a mixture of distorted edge and corner-sharing OAl2W2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one W(1), one W(2), and one Al(1) atom. is represented by the CIF file [CIF]
