Materials Data on MnTl2GeTe4 by Materials Project

MnTl2GeTe4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Mn2+ is bonded to four equivalent Te2- atoms to form MnTe4 tetrahedra that share edges with two equivalent GeTe4 tetrahedra. All Mn–Te bond lengths are 2.77 Å. Tl1+ is bonded in a 10-coordinate geometry to two equivalent Tl1+ and eight equivalent Te2- atoms. Both Tl–Tl bond lengths are 3.49 Å. There are four shorter (3.60 Å) and four longer (3.69 Å) Tl–Te bond lengths. Ge4+ is bonded to four equivalent Te2- atoms to form GeTe4 tetrahedra that share edges with two equivalent MnTe4 tetrahedra. All Ge–Te bond lengths are 2.65 Å. Te2- is bonded in a 2-coordinate geometry to one Mn2+, four equivalent Tl1+, and one Ge4+ atom.
