Ni2FeO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Fe(1) is bonded to four equivalent O(1) atoms to form FeO4 tetrahedra that share corners with twelve equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 58°. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra and edges with six equivalent Ni(1)O6 octahedra. O(1) is bonded to one Fe(1) and three equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing OFeNi3 trigonal pyramids.
