Materials Data on Cu2SnHgSe4 by Materials Project
Cu2HgSnSe4 is Stannite structured and crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Cu1+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent CuSe4 tetrahedra, corners with four equivalent HgSe4 tetrahedra, and corners with four equivalent SnSe4 tetrahedra. All Cu–Se bond lengths are 2.44 Å. Hg2+ is bonded to four equivalent Se2- atoms to form HgSe4 tetrahedra that share corners with four equivalent SnSe4 tetrahedra and corners with eight equivalent CuSe4 tetrahedra. All Hg–Se bond lengths are 2.72 Å. Sn4+ is bonded to four equivalent Se2- atoms to form SnSe4 tetrahedra that share corners with four equivalent HgSe4 tetrahedra and corners with eight equivalent CuSe4 tetrahedra. All Sn–Se bond lengths are 2.62 Å. Se2- is bonded to two equivalent Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SeCu2SnHg tetrahedra.
