YW3O8 crystallizes in the triclinic P-1 space group. Y(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form YO6 octahedra that share corners with eight equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. There are two inequivalent W sites. In the first W site, W(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second W site, W(2) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Y(1)O6 octahedra and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Y(1) and one W(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Y(1), one W(1), and one W(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent W(2) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Y(1) and two equivalent W(2) atoms.
