DySm(NiO3)4 crystallizes in the orthorhombic Cmmm space group. Dy(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four O(4,4,4) atoms. Sm(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four O(3,3) atoms. Ni(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 0-33°. There are seven inequivalent O sites. In the first O site, O(3) is bonded in a square co-planar geometry to two equivalent Sm(1) and two equivalent Ni(1) atoms. In the second O site, O(4) is bonded in a square co-planar geometry to two equivalent Dy(1) and two equivalent Ni(1) atoms. In the third O site, O(1) is bonded in a 3-coordinate geometry to one Sm(1) and two equivalent Ni(1) atoms. In the fourth O site, O(2) is bonded in a 3-coordinate geometry to one Dy(1) and two equivalent Ni(1) atoms. In the fifth O site, O(3) is bonded in a square co-planar geometry to two equivalent Sm(1) and two equivalent Ni(1) atoms.

In the seventh O site, O(4) is bonded in a square co-planar geometry to two equivalent Dy(1) and two equivalent Ni(1) atoms.
