Abstract

Graphical abstract: The sterics of β-diketiminato ligands affect the coordination chemistry of lead(II) complexes. Abstract: Three new β-diketiminatolead(II) chlorides have been synthesised, including [(BDIDMP )PbCl], [(BDIIPP )PbCl] and [(BDIPh )PbCl] (BDIDMP = [N{(2, 6-Me2 C6 H3 )C(Me)}2 CH], BDIIPP = [N{(4- i PrC6 H4 )C(Me)}2 CH] and BDIPh = [N{(C6 H5 )C(Me)}2 CH]). Addition of sodium or potassium-alkoxide salts to [(BDIIPP )PbCl] or [(BDIPh )PbCl] resulted in the unexpected formation of bis(β-diketiminato)lead(II) complexes, [(BDIIPP )2 Pb] and [(BDIPh )2 Pb], whereas addition to [(BDIDMP )PbCl] led to the expected lead alkoxo complex, [(BDIDMP )PbO t Bu]. The lead(II) triflate complex, [(BDIDMP )PbOTf], was synthesised by treatment of [(BDIDMP )PbCl] with AgOTf.
