✦ Synopsis

207Pb NMR spectroscopy was used to investigate the nature of aryllead(IV) tricarboxylate species in solution. The 207Pb chemical shifts of p-Br-and p-MeO-aryllead tricarboxylates were found to depend on both electronic (as measured by the of the parent acid) and steric e †ects of the neighbouring carboxylic acid ligands. pK
