FeCr2O4 is Spinel structured and crystallizes in the tetragonal I4_122 space group. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra and edges with six equivalent Cr(1)O6 octahedra. Fe(1) is bonded to four equivalent O(1) atoms to form FeO4 tetrahedra that share corners with twelve equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-61°. O(1) is bonded to three equivalent Cr(1) and one Fe(1) atom to form a mixture of distorted edge and corner-sharing OCr3Fe trigonal pyramids.
