A new bis‐triazacyclononane tris‐pyridyl N 9 ‐azacryptand ligand is prepared via a convenient one‐pot [2+3] condensation reaction between triazacyclononane and 2,6‐bis(bromomethyl) pyridine in the presence of M 2 CO 3 (M=Li, Na, K). The proton, lithium, sodium, potassium and lead(II) complexes of the ligand are characterised in the solid state. Preliminary solution‐phase competition experiments indicate that the cryptand ligand preferentially binds lead(II) in the presence of sodium, calcium, potassium and zinc cations in methanol solution.
