The crystal structure described by ZnS is Moissanite-4H-like structured and crystallizes in the hexagonal P6_3mc space group. There are four inequivalent Zn sites. In the first Zn site, Zn(1,4) is bonded to four equivalent S(1,3) atoms to form corner-sharing ZnS4 tetrahedra. In the second Zn site, Zn(2) is bonded to one S(4) and three equivalent S(1,3) atoms to form corner-sharing ZnS4 tetrahedra. In the third Zn site, Zn(3) is bonded to one S(5) and three equivalent S(4) atoms to form corner-sharing ZnS4 tetrahedra. In the fourth Zn site, Zn(5) is bonded to one S(2) and three equivalent S(5) atoms to form corner-sharing ZnS4 tetrahedra. There are four inequivalent S sites. In the first S site, S(1,3) is bonded to one Zn(1,4) and three equivalent Zn(2) atoms to form corner-sharing SZn4 tetrahedra. In the second S site, S(2) is bonded to one Zn(5) and three equivalent Zn(1,4) atoms to form corner-sharing SZn4 tetrahedra. In the third S site, S(4) is bonded to one Zn(2) and three equivalent Zn(3) atoms to form corner-sharing SZn4 tetrahedra. In the fourth S site, S(5) is bonded to one Zn(3) and three equivalent Zn(5) atoms to form corner-sharing SZn4 tetrahedra. is represented by the CIF file [CIF]
