Y2WO6 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. W(1) is bonded in a distorted pentagonal pyramidal geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Y(2), two equivalent Y(1), and one W(1) atom to form a mixture of edge and corner-sharing OY3W tetrahedra. In the second O site, O(2) is bonded in a water-like geometry to one Y(2) and one W(1) atom.
Y2WO6 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are four shorter (2.36 Å) and four longer (2.38 Å) Y(1)-O(1) bond lengths. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Y(2)-O(2) bond lengths are 2.25 Å. All Y(2)-O(1) bond lengths are 2.38 Å. W(1) is bonded in a distorted pentagonal pyramidal geometry to two equivalent O(2) and four equivalent O(1) atoms. Both W(1)-O(2) bond lengths are 1.88 Å. All W(1)-O(1) bond lengths are 2.03 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Y(2), two equivalent Y(1), and one W(1) atom to form a mixture of edge and corner-sharing OY3W tetrahedra. In the second O site, O(2) is bonded in a water-like geometry to one Y(2) and one W(1) atom.
