The compound described by ZnS is Moissanite 9R structured and crystallizes in the trigonal R3m space group. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one S(1) and three equivalent S(3) atoms to form corner-sharing ZnS4 tetrahedra. In the second Zn site, Zn(2) is bonded to one S(3) and three equivalent S(2) atoms to form corner-sharing ZnS4 tetrahedra. In the third Zn site, Zn(3) is bonded to one S(2) and three equivalent S(1) atoms to form corner-sharing ZnS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Zn(1) and three equivalent Zn(3) atoms to form corner-sharing SZn4 tetrahedra. In the second S site, S(2) is bonded to one Zn(3) and three equivalent Zn(2) atoms to form corner-sharing SZn4 tetrahedra. In the third S site, S(3) is bonded to one Zn(2) and three equivalent Zn(1) atoms to form corner-sharing SZn4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
