In the first Hg2+ site, Hg2+ is bonded to four S2- atoms to form HgS4 tetrahedra that share corners with four SnS4 tetrahedra and corners with eight CuS4 tetrahedra. There are two shorter (2.58 Å) and two longer (2.59 Å) Hg–S bond lengths. In the second Hg2+ site, Hg2+ is bonded to four S2- atoms to form HgS4 tetrahedra that share corners with four equivalent SnS4 tetrahedra and corners with eight CuS4 tetrahedra. There are two shorter (2.57 Å) and two longer (2.58 Å) Hg–S bond lengths. Zn2+ is bonded to four S2- atoms to form ZnS4 tetrahedra that share corners with four SnS4 tetrahedra and corners with eight CuS4 tetrahedra. There are two shorter (2.40 Å) and two longer (2.41 Å) Zn–S bond lengths. There are three inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to four S2- atoms to form SnS4 tetrahedra that share corners with two equivalent HgS4 tetrahedra, corners with two equivalent ZnS4 tetrahedra, and corners with eight CuS4 tetrahedra. There are two shorter (2.47 Å) and two longer (2.48 Å) Sn–S bond lengths. In the second Sn4+ site, Sn4+ is bonded to four S2- atoms to form SnS4 tetrahedra that share corners with four HgS4 tetrahedra and corners with eight CuS4 tetrahedra. There are three shorter (2.46 Å) and one longer (2.47 Å) Sn–S bond lengths. In the third Sn4+ site, Sn4+ is bonded to four S2- atoms to form SnS4 tetrahedra that share corners with four equivalent ZnS4 tetrahedra and corners with eight CuS4 tetrahedra. There are two shorter (2.49 Å) and two longer (2.50 Å) Sn–S bond lengths. There are ten inequivalent S2- sites. In the first S2- site, S2- is bonded to two Cu1+, one Zn2+, and one Sn4+ atom to form corner-sharing SZnCu2Sn tetrahedra. In the second S2- site, S2- is bonded to two Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra. In the third S2- site, S2- is bonded to two Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra. In the fourth S2- site, S2- is bonded to two Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra. In the fifth S2- site, S2- is bonded to two equivalent Cu1+, one Zn2+, and one Sn4+ atom to form corner-sharing SZnCu2Sn tetrahedra. In the sixth S2- site, S2- is bonded to two Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra. In the seventh S2- site, S2- is bonded to two equivalent Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra. In the eighth S2- site, S2- is bonded to two Cu1+, one Hg2+, and one Sn4+ atom to form corner-sharing SCu2SnHg tetrahedra.
