Heteroleptic lead(II)-halide complexes supported by a bulky iminoanilide ligand
The lead(II) chloride [{N^NiPr}PbCl] (1), where {N^N}− is a bulky, monoanionic, bidentate iminoanilide ligand, was synthesised by salt metathesis between [{N^NiPr}Li] and PbCl2. The complex was characterised by X-ray diffraction crystallography and 207Pb nuclear magnetic resonance (NMR) spectroscopy...

| Summary: | The lead(II) chloride [{N^NiPr}PbCl] (1), where {N^N}− is a bulky, monoanionic, bidentate iminoanilide ligand, was synthesised by salt metathesis between [{N^NiPr}Li] and PbCl2. The complex was characterised by X-ray diffraction crystallography and 207Pb nuclear magnetic resonance (NMR) spectroscopy. It exists in the molecular solid state as a monometallic three-coordinate species, with two independent, similar but not identical molecules per asymmetric unit. The differences between the first coordination sphere of 1 and that of Fulton’s structurally related β-diketiminato complex [{N^NiPr}PbCl] are illustrated. The synthesis of 1 offers a convenient handle in the still underdeveloped organometallic and inorganic chemistry of lead(II), as exemplified by the synthesis of the alkyl complex [{N^NiPr}PbCH(CH3)2] (3). The iodo complex [{N^NiPr}PbI] (2) was also synthesised, but, unlike 1, it showed limited stability in solution. |
