The crystal structure of Ph 3 Pb(S 2 COMe) ( 1 ) features a tetrahedrally coordinated lead centre existing within a distorted tetrahedral geometry defined by three ipso-carbon atoms and a sulphur atom derived from a monodentate xanthate ligand. The xanthate ligand is orientated to place the oxygen atom in close proximity to the lead atom rather than the formally thione-sulphur atom. The structure of Ph 3 Pb(S 2 CO-i-Pr) ( 2 ) comprises three independent molecules that differ from each other only in the relative orientations of the lead-bound phenyl groups, the distorted tetrahedral coordination geometries and orientation of the xanthate ligand resembles that observed in ( 1 ). Globally, the crystal structures are similar in that they both comprise supramolecular layers of molecules self-assembled through C—H … π(aryl) contacts.
