The imine ligand tris(2‐(propan‐2‐ylideneamino)‐ethyl)amine (imine 3 tren) had been prepared and characterized. The complexes [Na(imine 3 tren)(C 3 H 6 O)]BPh 4 , [Cu(imine 3 tren)]BPh 4 , [Zn(imine 3 tren)(CH 2 Cl 2 ) 2 ](BPh 4 ) 2 and [Ni(imine 3 tren)Br]BPh 4 were synthesized and structurally characterized. In contrast to copper(I) complexes with related tripodal ligands [Cu(imine 3 tren)]BPh 4 reacted quite slowly with dioxygen in solution and no “dioxygen adduct” complex could be spectroscopically detected. Cyclic voltammetry of this complex only showed an irreversible oxidation to a copper(II) species.
