The crystal structure described by NaEu(WO3)2 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. Na(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), and four equivalent O(3) atoms. Eu(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), and four equivalent O(4) atoms. W(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 26-29°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), one Eu(1), and two equivalent W(1) atoms to form distorted corner-sharing ONaEuW2 tetrahedra. In the second O site, O(2) is bonded to one Na(1), one Eu(1), and two equivalent W(1) atoms to form distorted corner-sharing ONaEuW2 tetrahedra. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Na(1), one Eu(1), and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Na(1), two equivalent Eu(1), and two equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
