The material structure described by NaEuZr2O6 crystallizes in the orthorhombic Cmmm space group. Na(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Eu(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Zr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1), two equivalent Eu(1), and two equivalent Zr(1) atoms to form distorted ONa2Eu2Zr2 octahedra that share corners with six equivalent O(1)Na2Eu2Zr2 octahedra, corners with four equivalent O(3)Eu2Zr2 tetrahedra, edges with four equivalent O(1)Na2Eu2Zr2 octahedra, and edges with four equivalent O(3)Eu2Zr2 tetrahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent Zr(1) atoms. In the third O site, O(3) is bonded to two equivalent Eu(1) and two equivalent Zr(1) atoms to form distorted OEu2Zr2 tetrahedra that share corners with four equivalent O(1)Na2Eu2Zr2 octahedra, corners with six equivalent O(3)Eu2Zr2 tetrahedra, edges with four equivalent O(1)Na2Eu2Zr2 octahedra, and  an edgeedge with one O(3)Eu2Zr2 tetrahedra. The corner-sharing octahedral tilt angles are 67°. is represented by the CIF file [CIF]
