The structure described by YW2O9 crystallizes in the monoclinic P2_1/m space group. Y(1) is bonded in a 8-coordinate geometry to one O(2), one O(6), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. W(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form distorted edge-sharing WO6 octahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Y(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Y(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Y(1) and two equivalent W(1) atoms. In the fifth O site, O(5) is bonded in a linear geometry to one Y(1) and one W(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one Y(1) atom. is represented by the CIF file [CIF]
