CoNi2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Co(1) is bonded to four equivalent S(1) atoms to form CoS4 tetrahedra that share corners with twelve equivalent Ni(1)S6 octahedra. The corner-sharing octahedral tilt angles are 57°. Ni(1) is bonded to six equivalent S(1) atoms to form NiS6 octahedra that share corners with six equivalent Co(1)S4 tetrahedra and edges with six equivalent Ni(1)S6 octahedra. S(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1) and three equivalent Ni(1) atoms.
