Materials Data on Al2HgO4 by Materials Project
HgAl2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Hg2+ is bonded to four equivalent O2- atoms to form HgO4 tetrahedra that share corners with twelve equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 63°. All Hg–O bond lengths are 2.19 Å. Al3+ is bonded to six equivalent O2- atoms to form distorted AlO6 octahedra that share corners with six equivalent HgO4 tetrahedra and edges with six equivalent AlO6 octahedra. All Al–O bond lengths are 1.97 Å. O2- is bonded to one Hg2+ and three equivalent Al3+ atoms to form a mixture of distorted edge and corner-sharing OAl3Hg tetrahedra.
