The structure described by PbS is Halite, Rock Salt structured and crystallizes in the orthorhombic Pnma space group. Pb(1) is bonded to six equivalent S(1) atoms to form a mixture of corner and edge-sharing PbS6 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to six equivalent Pb(1) atoms to form a mixture of corner and edge-sharing SPb6 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
