ZnS is Zincblende, Sphalerite-like structured and crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Zn sites. In the first Zn site, Zn(1,5) is bonded to one S(1,7) and three equivalent S(2) atoms to form corner-sharing ZnS4 tetrahedra. In the second Zn site, Zn(2,3,4,6) is bonded to one S(3,4,5,6) and three equivalent S(1,7) atoms to form corner-sharing ZnS4 tetrahedra. In the third Zn site, Zn(7) is bonded to one S(2) and three equivalent S(1,7) atoms to form corner-sharing ZnS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1,7) is bonded to one Zn(1,5) and three equivalent Zn(7) atoms to form corner-sharing SZn4 tetrahedra. In the second S site, S(2) is bonded to one Zn(7) and three equivalent Zn(1,5) atoms to form corner-sharing SZn4 tetrahedra. In the third S site, S(3,4,5,6) is bonded to four equivalent Zn(2,3,4,6) atoms to form corner-sharing SZn4 tetrahedra.
