A new type of heteroleptic complex of divalent lead and synthesis of the P-plumbyleniophosphasilene, R2Si=P-Pb(L): (L = beta-diketiminate).
The synthesis and structures of the first heteroleptic beta-diketiminato complexes of lead(II) with terminal phenolato, bis(trimethylsilyl)amido, bis(trimethylsilyl)phosphanido and silylidenephosphanido ligands are reported; 207Pb NMR spectroscopic data indicate that lead(II) can serve as a sigma-donor or acceptor centre, depending on the electronegativity of the terminal ligand.
