The material described by SrEu(WO3)2 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(4), three equivalent O(2), and four equivalent O(3) atoms. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(1), 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 22-28°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Sr(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Sr(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 Sr(1), two equivalent Eu(1), and two equivalent W(1) atoms. is represented by the CIF card [CIF]
