摘要：

The reaction of the tetradentate tripod-like ligand N(CH2CH2NMe2)(3) (trenMe(6)) with Pb(CH3COO)(2). 3H(2)O in presence of Na(BPh4) allows the formation of the complex [(trenMe(6))Pb(O2CCH3)](2)(BPh4)(2). The complex displays a dimeric structure where each lead metal is linked by one trenMe(6) ligand and by three oxygens of two bridging acetate groups in a hepta-coordination. The presence of a void in the angular distribution of the ligands around the metal as well as the values of the Pb-L distances, with those opposite to the void significantly shorter than the others, are indicative of the presence of a stereochemically active lone pair on Pb(II).
