WGa2O6 crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted WO6 octahedra that share corners with four equivalent Ga(2)O6 octahedra and  an edgeedge with one Ga(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-53°. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. In the second Ga site, Ga(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form GaO6 octahedra that share corners with four equivalent W(1)O6 octahedra and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-53°. In the third Ga site, Ga(3) is bonded in a 4-coordinate geometry to two equivalent O(3), two equivalent O(4), and two equivalent O(6) atoms. There are six inequivalent O sites.

In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one W(1), one Ga(1), one Ga(2), and one Ga(3) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one W(1), one Ga(2), and one Ga(3) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one W(1) and one Ga(2) atom. In the sixth O site, O(6) is bonded in a trigonal non-coplanar geometry to one W(1), one Ga(2), and one Ga(3) atom.
