Materials Data on Ga2HgTe4 by Materials Project
HgGa2Te4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Hg2+ is bonded to four equivalent Te2- atoms to form HgTe4 tetrahedra that share corners with eight equivalent GaTe4 tetrahedra. All Hg–Te bond lengths are 2.88 Å. Ga3+ is bonded to four equivalent Te2- atoms to form GaTe4 tetrahedra that share corners with four equivalent HgTe4 tetrahedra and corners with four equivalent GaTe4 tetrahedra. All Ga–Te bond lengths are 2.69 Å. Te2- is bonded in a distorted trigonal non-coplanar geometry to one Hg2+ and two equivalent Ga3+ atoms.
