HgTl2GeTe4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Hg2+ is bonded to four equivalent Te2- atoms to form distorted HgTe4 tetrahedra that share edges with two equivalent GeTe4 tetrahedra. All Hg–Te bond lengths are 2.91 Å. Tl1+ is bonded in a 10-coordinate geometry to two equivalent Tl1+ and eight equivalent Te2- atoms. Both Tl–Tl bond lengths are 3.60 Å. There are four shorter (3.56 Å) and four longer (3.75 Å) Tl–Te bond lengths. Ge4+ is bonded to four equivalent Te2- atoms to form GeTe4 tetrahedra that share edges with two equivalent HgTe4 tetrahedra. All Ge–Te bond lengths are 2.66 Å. Te2- is bonded in a 6-coordinate geometry to one Hg2+, four equivalent Tl1+, and one Ge4+ atom.
