HgAl2O4 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 Al(1)O6 octahedra. The corner-sharing octahedral tilt angles are 63°. Al(1) is bonded to six equivalent O(1) atoms to form distorted AlO6 octahedra that share corners with six equivalent Hg(1)O4 tetrahedra and edges with six equivalent Al(1)O6 octahedra. O(1) is bonded to one Hg(1) and three equivalent Al(1) atoms to form a mixture of corner and edge-sharing OAl3Hg tetrahedra.
