WIn2O6 crystallizes in the orthorhombic P2_12_12_1 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 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 49-53°. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to one O(2), one O(4), one O(6), and two equivalent O(1) atoms. In the second In site, In(2) is bonded to one O(2), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form InO6 octahedra that share corners with two equivalent In(2)O6 octahedra, 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 49-57°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one W(1) and two equivalent In(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one W(1), one In(1), and one In(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one W(1) and one In(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one W(1), one In(1), and one In(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent In(2) atoms. In the sixth O site, O(6) is bonded in a trigonal non-coplanar geometry to one W(1), one In(1), and one In(2) atom.
