The structure described by PbS is alpha As-derived structured and crystallizes in the orthorhombic Pnma space group. Pb(1) is bonded to six equivalent S(1) atoms to form a mixture of distorted corner and edge-sharing PbS6 octahedra. The corner-sharing octahedral tilt angles range from 9-12°. S(1) is bonded to six equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing SPb6 octahedra. The corner-sharing octahedral tilt angles range from 6-9°. is represented by the CIF file [CIF]
