The material structure described by Sr2FeWO6 crystallizes in the triclinic P-1 space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. 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 Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-22°. Fe(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form FeO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-22°. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1), one W(1), and one Fe(1) atom to form a mixture of distorted corner and edge-sharing OSr4FeW octahedra. The corner-sharing octahedral tilt angles range from 0-4°. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one W(1), and one Fe(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one W(1), and one Fe(1) atom. is represented by the CIF file [CIF]
