ZnS is Zincblende, Sphalerite-like structured and crystallizes in the trigonal R3m space group. There are four inequivalent Zn sites. In the first Zn site, Zn(1,3,4,6,7,8,10,11,12) is bonded to one S(1,2,5,6,7,8,9,10,11,12) and three equivalent S(4) atoms to form corner-sharing ZnS4 tetrahedra. In the second Zn site, Zn(2) is bonded to one S(3) and three equivalent S(1,2,5,6,7,8,9,10,11,12) atoms to form corner-sharing ZnS4 tetrahedra. In the third Zn site, Zn(5) is bonded to four equivalent S(1,2,5,6,7,8,9,10,11,12) atoms to form corner-sharing ZnS4 tetrahedra. In the fourth Zn site, Zn(9) is bonded to one S(1,2,5,6,7,8,9,10,11,12) and three equivalent S(3) atoms to form corner-sharing ZnS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1,2,5,6,7,8,9,10,11,12) is bonded to four equivalent Zn(1,3,4,6,7,8,10,11,12) atoms to form corner-sharing SZn4 tetrahedra. In the second S site, S(3) is bonded to one Zn(2) and three equivalent Zn(9) atoms to form corner-sharing SZn4 tetrahedra. In the third S site, S(4) is bonded to four equivalent Zn(1,3,4,6,7,8,10,11,12) atoms to form corner-sharing SZn4 tetrahedra.

The Zn(1,3,4,6,7,8,10,11,12)-S(1,2,5,6,7,8,9,10,11,12) bond length is 2.35 Å. All Zn(1,3,4,6,7,8,10,11,12)-S(4) bond lengths are 2.37 Å. In the second Zn site, Zn(2) is bonded to one S(3) and three equivalent S(1,2,5,6,7,8,9,10,11,12) atoms to form corner-sharing ZnS4 tetrahedra. The Zn(2)-S(3) bond length is 2.35 Å.

There is one shorter (2.35 Å) and three longer (2.37 Å) Zn(5)-S(1,2,5,6,7,8,9,10,11,12) bond lengths. In the fourth Zn site, Zn(9) is bonded to one S(1,2,5,6,7,8,9,10,11,12) and three equivalent S(3) atoms to form corner-sharing ZnS4 tetrahedra. The Zn(9)-S(1,2,5,6,7,8,9,10,11,12) bond length is 2.36 Å. All Zn(9)-S(3) bond lengths are 2.37 Å. There are three inequivalent S sites. In the first S site, S(1,2,5,6,7,8,9,10,11,12) is bonded to four equivalent Zn(1,3,4,6,7,8,10,11,12) atoms to form corner-sharing SZn4 tetrahedra.
