HgGa2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Hg(1) is bonded to four equivalent O(1) atoms to form HgO4 tetrahedra that share corners with twelve equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Hg(1)O4 tetrahedra and edges with six equivalent Ga(1)O6 octahedra. O(1) is bonded to one Hg(1) and three equivalent Ga(1) atoms to form a mixture of edge and corner-sharing OGa3Hg tetrahedra.
