HgHgO(NiF3)2 crystallizes in the cubic Fd-3m space group. The structure consists of one HgHgO framework and one NiF3 framework. In the HgHgO framework, Hg(1) is bonded in a distorted linear geometry to two equivalent O(1) atoms. O(1) is bonded to four equivalent Hg(1) atoms to form corner-sharing OHg4 tetrahedra. In the NiF3 framework, Ni(1) is bonded to six equivalent F(1) atoms to form corner-sharing NiF6 octahedra. The corner-sharing octahedral tilt angles are 45°. F(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ni(1) atoms.
