WIn2O6 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 In(2)O6 octahedra and  an edgeedge with one In(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-52°. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms.
