NiMn2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Ni(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. Ni(1) is bonded to four equivalent O(1) atoms to form NiO4 tetrahedra that share corners with twelve equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 57°. O(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Mn(1) and one Ni(1) atom.
