The material structure described by Sr8MnFe7O24 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Sr(1) is bonded to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra,  a faceface with one Mn(1)O6 octahedra,  a faceface with one Fe(3)O6 octahedra, faces with three equivalent Fe(1)O6 octahedra, and faces with three equivalent Fe(2)O6 octahedra. Mn(1) is bonded to six equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Fe(2)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with two equivalent Fe(3)O6 octahedra, corners with four equivalent Fe(2)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Fe site, Fe(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with four equivalent Fe(1)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the third Fe site, Fe(3) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1), one Fe(1), and one Fe(3) atom to form a mixture of distorted edge, corner, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second O site, O(2) is bonded to four equivalent Sr(1), one Fe(1), and one Fe(2) atom to form a mixture of distorted edge, corner, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent Sr(1), one Mn(1), and one Fe(2) atom. is represented by the CIF file [CIF]
