Dy3SbO3 crystallizes in the monoclinic C2/m space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1), one O(1), and three equivalent O(3) atoms. In the second Dy site, Dy(2) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(2), one O(3), and two equivalent O(1) atoms. In the third Dy site, Dy(3) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(1), and three equivalent O(2) atoms. Sb(1) is bonded in a body-centered cubic geometry to two equivalent Dy(2), two equivalent Dy(3), and four equivalent Dy(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Dy(1), one Dy(3), and two equivalent Dy(2) atoms to form a mixture of distorted corner and edge-sharing ODy4 trigonal pyramids. In the second O site, O(2) is bonded to one Dy(2) and three equivalent Dy(3) atoms to form a mixture of corner and edge-sharing ODy4 trigonal pyramids. In the third O site, O(3) is bonded to one Dy(2) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing ODy4 tetrahedra.

In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1), one O(1), and three equivalent O(3) atoms. There are two shorter (3.37 Å) and two longer (3.42 Å) Dy(1)-Sb(1) bond lengths. The Dy(1)-O(1) bond length is 2.68 Å. There are two shorter (2.25 Å) and one longer (2.27 Å) Dy(1)-O(3) bond length. In the second Dy site, Dy(2) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(2), one O(3), and two equivalent O(1) atoms. Both Dy(2)-Sb(1) bond lengths are 3.24 Å. The Dy(2)-O(2) bond length is 2.30 Å. The Dy(2)-O(3) bond length is 2.20 Å. Both Dy(2)-O(1) bond lengths are 2.26 Å. In the third Dy site, Dy(3) is bonded in a distorted see-saw-like geometry to two equivalent Sb(1), one O(1), and three equivalent O(2) atoms. Both Dy(3)-Sb(1) bond lengths are 3.19 Å.
