Hg2Cu2F6S crystallizes in the cubic Fd-3m space group. The structure consists of one CuF3 framework and one Hg2S framework. In the CuF3 framework, Cu(1) is bonded to six equivalent F(1) atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedral tilt angles are 42°. F(1) is bonded in a bent 150 degrees geometry to two equivalent Cu(1) atoms. In the Hg2S framework, Hg(1) is bonded in a linear geometry to two equivalent S(1) atoms. S(1) is bonded to four equivalent Hg(1) atoms to form corner-sharing SHg4 tetrahedra.
