Y(WO2)2 is Spinel structured and crystallizes in the trigonal R-3m space group. Y(1) is bonded to one O(2) and three equivalent O(1) atoms to form YO4 tetrahedra that share corners with three equivalent W(2)O6 octahedra and corners with nine equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-61°. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Y(1)O4 tetrahedra, edges with two equivalent W(2)O6 octahedra, and edges with four equivalent W(1)O6 octahedra. In the second W site, W(2) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Y(1)O4 tetrahedra and edges with six equivalent W(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Y(1), one W(2), and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing OYW3 trigonal pyramids. In the second O site, O(2) is bonded to one Y(1) and three equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing OYW3 tetrahedra.
