radiopharmaceutical applications. 1H NMRspectroscopy was used to study each metal–ligand complex in the solution state. The 1H NMR spectrum of [Pb(DTPAm)]2+ revealed minimal isomerization and fluxional behaviour compared to [Pb(EGTAm)]2+ and [Pb(ampam)]2+, both of which showed fewer spectral changes indicative of less static behaviour. The solid-state coordination properties of each complex were also examined from
