The structure described by VAl(WO4)2 crystallizes in the triclinic P-1 space group. V(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted VO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with four equivalent Al(1)O6 octahedra, and edges with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-67°. W(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted WO6 octahedra that share  a cornercorner with one V(1)O6 octahedra, corners with four equivalent Al(1)O6 octahedra, edges with two equivalent V(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-58°. Al(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form AlO6 octahedra that share corners with four equivalent V(1)O6 octahedra and corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-67°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one Al(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one V(1), one W(1), and one Al(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one V(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one V(1), two equivalent W(1), and one Al(1) atom. is represented by the CIF file [CIF]
