A new type of heteroleptic complex of divalent lead and synthesis of the P-plumbyleniophosphasilene, R2SiP–Pb(L): (L = β-diketiminate)

Abstract

The synthesis and structures of the first heteroleptic β-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 σ-donor or acceptor centre, depending on the electronegativity of the terminal ligand.
