The material described by Sr2FeSbO6 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent O(1) and eight equivalent O(2) atoms. Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-17°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-17°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to four equivalent Sr(1), one Fe(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Fe(1), and one Sb(1) atom. is represented by the CIF file [CIF]
