The material described by K2HgSnTe4 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Hg(1) is bonded to four equivalent Te(1) atoms to form HgTe4 tetrahedra that share edges with two equivalent Sn(1)Te4 tetrahedra. Sn(1) is bonded to four equivalent Te(1) atoms to form SnTe4 tetrahedra that share edges with two equivalent Hg(1)Te4 tetrahedra. Te(1) is bonded in a distorted hexagonal planar geometry to four equivalent K(1), one Hg(1), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
