The compound described by DyYO3 crystallizes in the hexagonal P6_3cm space group. Dy(1) is bonded to one O(1), one O(2), one O(4), and two equivalent O(3) atoms to form corner-sharing DyO5 trigonal bipyramids. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to one O(3), three equivalent O(1), and three equivalent O(2) atoms. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to one O(4), three equivalent O(1), and three equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Dy(1), one Y(2), and two equivalent Y(1) atoms to form ODyY3 tetrahedra that share corners with two equivalent O(4)Dy3Y tetrahedra, corners with four equivalent O(2)DyY3 tetrahedra, corners with six equivalent O(1)DyY3 tetrahedra, edges with three equivalent O(2)DyY3 tetrahedra, and edges with two equivalent O(3)Dy3Y trigonal pyramids. In the second O site, O(2) is bonded to one Dy(1), one Y(2), and two equivalent Y(1) atoms to form ODyY3 tetrahedra that share corners with four equivalent O(1)DyY3 tetrahedra, corners with six equivalent O(2)DyY3 tetrahedra, corners with four equivalent O(3)Dy3Y trigonal pyramids,  an edgeedge with one O(4)Dy3Y tetrahedra, and edges with three equivalent O(1)DyY3 tetrahedra. In the third O site, O(3) is bonded to three equivalent Dy(1) and one Y(1) atom to form distorted ODy3Y trigonal pyramids that share corners with three equivalent O(4)Dy3Y tetrahedra, corners with six equivalent O(2)DyY3 tetrahedra, corners with three equivalent O(3)Dy3Y trigonal pyramids, and edges with three equivalent O(1)DyY3 tetrahedra. In the fourth O site, O(4) is bonded to three equivalent Dy(1) and one Y(2) atom to form distorted ODy3Y tetrahedra that share corners with six equivalent O(1)DyY3 tetrahedra, corners with six equivalent O(3)Dy3Y trigonal pyramids, and edges with three equivalent O(2)DyY3 tetrahedra. is represented by the CIF file [CIF]
