The compound described by HgZnS2 is Enargite-like structured and crystallizes in the trigonal R3m space group. Hg(1) is bonded to one S(1) and three equivalent S(2) atoms to form HgS4 tetrahedra that share corners with six equivalent Hg(1)S4 tetrahedra and corners with six equivalent Zn(1)S4 tetrahedra. Zn(1) is bonded to one S(2) and three equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with six equivalent Hg(1)S4 tetrahedra and corners with six equivalent Zn(1)S4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Hg(1) and three equivalent Zn(1) atoms to form SZn3Hg tetrahedra that share corners with six equivalent S(1)Zn3Hg tetrahedra and corners with six equivalent S(2)ZnHg3 tetrahedra. In the second S site, S(2) is bonded to three equivalent Hg(1) and one Zn(1) atom to form SZnHg3 tetrahedra that share corners with six equivalent S(1)Zn3Hg tetrahedra and corners with six equivalent S(2)ZnHg3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
