DyNd(NiO3)4 crystallizes in the orthorhombic Amm2 space group. Dy(1) is bonded in a 4-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Nd(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Ni(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 17-32°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Nd(1) and two equivalent Ni(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Dy(1) and two equivalent Ni(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Dy(1), one Nd(1), and two equivalent Ni(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Nd(1) and two equivalent Ni(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Dy(1) and two equivalent Ni(1) atoms.
