The material described by DyGaO3 crystallizes in the hexagonal P6_3cm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(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 Dy site, Dy(2) is bonded to one O(4), three equivalent O(1), and three equivalent O(2) atoms to form distorted DyO7 pentagonal bipyramids that share corners with three equivalent Ga(1)O5 trigonal bipyramids and edges with three equivalent Ga(1)O5 trigonal bipyramids. Ga(1) is bonded to one O(1), one O(2), one O(4), and two equivalent O(3) atoms to form GaO5 trigonal bipyramids that share  a cornercorner with one Dy(2)O7 pentagonal bipyramid, corners with six equivalent Ga(1)O5 trigonal bipyramids, and  an edgeedge with one Dy(2)O7 pentagonal bipyramid. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Dy(2), two equivalent Dy(1), and one Ga(1) atom to form ODy3Ga tetrahedra that share corners with four equivalent O(2)Dy3Ga tetrahedra, corners with six equivalent O(1)Dy3Ga tetrahedra, corners with two equivalent O(4)DyGa3 trigonal pyramids, edges with three equivalent O(2)Dy3Ga tetrahedra, and edges with two equivalent O(3)DyGa3 trigonal pyramids. In the second O site, O(2) is bonded to one Dy(2), two equivalent Dy(1), and one Ga(1) atom to form distorted ODy3Ga tetrahedra that share corners with four equivalent O(1)Dy3Ga tetrahedra, corners with six equivalent O(2)Dy3Ga tetrahedra, corners with four equivalent O(3)DyGa3 trigonal pyramids, edges with three equivalent O(1)Dy3Ga tetrahedra, and  an edgeedge with one O(4)DyGa3 trigonal pyramid. In the third O site, O(3) is bonded to one Dy(1) and three equivalent Ga(1) atoms to form ODyGa3 trigonal pyramids that share corners with six equivalent O(2)Dy3Ga tetrahedra, corners with three equivalent O(3)DyGa3 trigonal pyramids, corners with three equivalent O(4)DyGa3 trigonal pyramids, and edges with three equivalent O(1)Dy3Ga tetrahedra. In the fourth O site, O(4) is bonded to one Dy(2) and three equivalent Ga(1) atoms to form ODyGa3 trigonal pyramids that share corners with six equivalent O(1)Dy3Ga tetrahedra, corners with six equivalent O(3)DyGa3 trigonal pyramids, and edges with three equivalent O(2)Dy3Ga tetrahedra. is represented by the CIF card [CIF]
