The structure described by PbS crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of four PbS clusters. Pb(1) is bonded in a distorted single-bond geometry to one S(1) atom. S(1) is bonded in a single-bond geometry to one Pb(1) atom. is represented by the CIF file [CIF]
