twist-chair conformer in the solidstate. Solution state NMR experiments highlight a conformational preference for the bulky aryl groups to adopt an equatorial site, pre-disposing the ligand to metal binding, by adoption of a conformation that creates a facial array of the ligand nitrogen atoms. This ligandconformation averts the formation of less stable metal complexes with differing ligation modes

Pre-organised tricarboxylate ligands based on 6-amino-perhydro-1,4-diazepine bind 68Ga rapidly and selectively in acetate buffer at pH 4 to 7, forming kinetically stable complexes suitable for use in PET imaging.
