Sr4ReFe3O12 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Im-3m space group. Sr(1) is bonded to six equivalent O(1) 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, faces with two equivalent Re(1)O6 octahedra, and faces with six equivalent Fe(1)O6 octahedra. Re(1) is bonded to six equivalent O(2) atoms to form ReO6 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. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with two equivalent Re(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. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1) and two equivalent Fe(1) atoms to form distorted OSr4Fe2 octahedra that share corners with eight equivalent O(2)Sr4FeRe octahedra, corners with fourteen equivalent O(1)Sr4Fe2 octahedra, edges with four equivalent O(2)Sr4FeRe octahedra, faces with four equivalent O(1)Sr4Fe2 octahedra, and faces with four equivalent O(2)Sr4FeRe octahedra. The corner-sharing octahedral tilt angles range from 0-62°. In the second O site, O(2) is bonded to four equivalent Sr(1), one Re(1), and one Fe(1) atom to form distorted OSr4FeRe octahedra that share corners with eight equivalent O(1)Sr4Fe2 octahedra, corners with fourteen equivalent O(2)Sr4FeRe octahedra, edges with four equivalent O(1)Sr4Fe2 octahedra, faces with four equivalent O(1)Sr4Fe2 octahedra, and faces with four equivalent O(2)Sr4FeRe octahedra. The corner-sharing octahedral tilt angles range from 0-62°.
