The material described by HgGa2Te4 crystallizes in the tetragonal I-42m space group. Hg(1) is bonded to four equivalent Te(1) atoms to form HgTe4 tetrahedra that share corners with eight equivalent Ga(1)Te4 tetrahedra. 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(1)Te4 tetrahedra. Te(1) is bonded in a trigonal non-coplanar geometry to one Hg(1) and two equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
