The material structure described by HgGa2Te4 crystallizes in the tetragonal I-4 space group. Hg(1) is bonded to four equivalent Te(1) atoms to form HgTe4 tetrahedra that share corners with four equivalent Ga(1)Te4 tetrahedra and corners with four equivalent Ga(2)Te4 tetrahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with four equivalent Hg(1)Te4 tetrahedra and corners with four equivalent Ga(2)Te4 tetrahedra. In the second Ga site, Ga(2) is bonded to four equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with four equivalent Hg(1)Te4 tetrahedra and corners with four equivalent Ga(1)Te4 tetrahedra. Te(1) is bonded in a trigonal non-coplanar geometry to one Hg(1), one Ga(1), and one Ga(2) atom. is represented by the CIF file [CIF]
