HgZnTe2 is Lavarevi\'{c}ite-like structured and crystallizes in the tetragonal P-4m2 space group. Hg(1) is bonded to four equivalent Te(1) atoms to form HgTe4 tetrahedra that share corners with four equivalent Hg(1)Te4 tetrahedra and corners with eight equivalent Zn(1)Te4 tetrahedra. Zn(1) is bonded to four equivalent Te(1) atoms to form ZnTe4 tetrahedra that share corners with four equivalent Zn(1)Te4 tetrahedra and corners with eight equivalent Hg(1)Te4 tetrahedra. Te(1) is bonded to two equivalent Hg(1) and two equivalent Zn(1) atoms to form corner-sharing TeZn2Hg2 tetrahedra.
