The crystal structure described by HgTl2GeTe4 crystallizes in the tetragonal I-42m space group. The structure consists of a HgTl2GeTe4 framework. Hg(1) is bonded to four equivalent Te(1) atoms to form distorted HgTe4 tetrahedra that share edges with two equivalent Ge(1)Te4 tetrahedra. Tl(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) atoms. Ge(1) is bonded to four equivalent Te(1) atoms to form GeTe4 tetrahedra that share edges with two equivalent Hg(1)Te4 tetrahedra. Te(1) is bonded in a 2-coordinate geometry to one Hg(1), two equivalent Tl(1), and one Ge(1) atom. is represented by the CIF file [CIF]
