Y2HgO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Y(1) is bonded to six equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Hg(1)O4 tetrahedra and edges with six equivalent Y(1)O6 octahedra. Hg(1) is bonded to four equivalent O(1) atoms to form HgO4 tetrahedra that share corners with twelve equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. O(1) is bonded to three equivalent Y(1) and one Hg(1) atom to form a mixture of distorted corner and edge-sharing OY3Hg tetrahedra.
