Materials Data on ZnHgTe2 by Materials Project
HgZnTe2 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Hg2+ is bonded to four Te2- atoms to form HgTe4 tetrahedra that share corners with six equivalent HgTe4 tetrahedra and corners with six equivalent ZnTe4 tetrahedra. There are three shorter (2.84 Å) and one longer (2.87 Å) Hg–Te bond lengths. Zn2+ is bonded to four Te2- atoms to form ZnTe4 tetrahedra that share corners with six equivalent HgTe4 tetrahedra and corners with six equivalent ZnTe4 tetrahedra. There are one shorter (2.67 Å) and three longer (2.75 Å) Zn–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to one Hg2+ and three equivalent Zn2+ atoms to form corner-sharing TeZn3Hg tetrahedra. In the second Te2- site, Te2- is bonded to three equivalent Hg2+ and one Zn2+ atom to form corner-sharing TeZnHg3 tetrahedra.
