The material structure described by WAlO3 crystallizes in the hexagonal P6_3/mmc space group. W(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form WO5 trigonal bipyramids that share corners with six equivalent Al(1)O6 octahedra and corners with six equivalent W(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 66°. Al(1) is bonded to six equivalent O(1) atoms to form distorted AlO6 octahedra that share corners with six equivalent W(1)O5 trigonal bipyramids and edges with six equivalent Al(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to three equivalent W(1) atoms. In the second O site, O(1) is bonded to one W(1) and three equivalent Al(1) atoms to form a mixture of edge and corner-sharing OAl3W tetrahedra. is represented by the CIF card [CIF]
