The crystal structure described by HgZnTe2 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal R3m space group. Hg(1) is bonded to one Te(1) and three equivalent Te(2) atoms to form HgTe4 tetrahedra that share corners with six equivalent Hg(1)Te4 tetrahedra and corners with six equivalent Zn(1)Te4 tetrahedra. Zn(1) is bonded to one Te(2) and three equivalent Te(1) atoms to form ZnTe4 tetrahedra that share corners with six equivalent Hg(1)Te4 tetrahedra and corners with six equivalent Zn(1)Te4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one Hg(1) and three equivalent Zn(1) atoms to form TeZn3Hg tetrahedra that share corners with six equivalent Te(1)Zn3Hg tetrahedra and corners with six equivalent Te(2)ZnHg3 tetrahedra. In the second Te site, Te(2) is bonded to three equivalent Hg(1) and one Zn(1) atom to form TeZnHg3 tetrahedra that share corners with six equivalent Te(1)Zn3Hg tetrahedra and corners with six equivalent Te(2)ZnHg3 tetrahedra. is represented by the CIF card [CIF]
