The compound described by NaEu(NiO3)4 crystallizes in the orthorhombic Amm2 space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(3) and two equivalent O(5) atoms. Eu(1) is bonded in a 10-coordinate geometry to two equivalent O(2), 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 21-39°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Eu(1) and two equivalent Ni(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Eu(1) and two equivalent Ni(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Na(1) and two equivalent Ni(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Ni(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
