The material described by Sr2EuWO6 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(3), three equivalent O(1), and three equivalent O(2) atoms. Eu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form EuO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 31-34°. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 31-34°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Eu(1), and one W(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Eu(1), and one W(1) atom. In the third O site, O(3) is bonded to two equivalent Sr(1), one Eu(1), and one W(1) atom to form distorted corner-sharing OSr2EuW tetrahedra. is represented by the CIF card [CIF]
