GeNi2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with six equivalent Ni(1)O6 octahedra. Ge(1) is bonded to four equivalent O(1) atoms to form GeO4 tetrahedra that share corners with twelve equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 55°. O(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ni(1) and one Ge(1) atom.
