The material structure described by CrFe3Zn2O8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent O(2) atoms to form CrO6 octahedra that share corners with six equivalent Zn(1)O4 tetrahedra and edges with six equivalent Fe(1)O6 octahedra. 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 Zn(1)O4 tetrahedra, edges with two equivalent Cr(1)O6 octahedra, and edges with four equivalent Fe(1)O6 octahedra. Zn(1) is bonded to one O(1) and three equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with three equivalent Cr(1)O6 octahedra and corners with nine equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Fe(1) and one Zn(1) atom to form distorted OZnFe3 trigonal pyramids that share corners with three equivalent O(1)ZnFe3 trigonal pyramids, corners with nine equivalent O(2)ZnCrFe2 trigonal pyramids, and edges with three equivalent O(2)ZnCrFe2 trigonal pyramids. In the second O site, O(2) is bonded to one Cr(1), two equivalent Fe(1), and one Zn(1) atom to form distorted OZnCrFe2 trigonal pyramids that share corners with three equivalent O(1)ZnFe3 trigonal pyramids, corners with nine equivalent O(2)ZnCrFe2 trigonal pyramids,  an edgeedge with one O(1)ZnFe3 trigonal pyramid, and edges with two equivalent O(2)ZnCrFe2 trigonal pyramids. is represented by the CIF file [CIF]
