Hg2SeS is Chalcopyrite-like structured and crystallizes in the tetragonal P-4m2 space group. Hg(1) is bonded to two equivalent Se(1) and two equivalent S(1) atoms to form corner-sharing HgSe2S2 tetrahedra. Se(1) is bonded to four equivalent Hg(1) atoms to form SeHg4 tetrahedra that share corners with four equivalent Se(1)Hg4 tetrahedra and corners with eight equivalent S(1)Hg4 tetrahedra. S(1) is bonded to four equivalent Hg(1) atoms to form SHg4 tetrahedra that share corners with four equivalent S(1)Hg4 tetrahedra and corners with eight equivalent Se(1)Hg4 tetrahedra.
