Regarding Li/Na perchlorates, which are not only environmental hazards but also useful oxidants in chemical synthesis, an efficient Li–Na perchlorate separation method has not been reported due to lack of a ligand which can selectively coordinate with one of the two. Herein, we report an efficient Li–Na perchlorate separation by using our hexadentate ligand N,N′,N″-tris-(2-N-diethylaminoethyl)-1,4,7-triaza-cyclononane (DETAN), which can selectively coordinate with LiClO4at room temperature to form a monomer in excellent yield but does not coordinate with NaClO4even at elevated temperature. The structure of the monomeric complex, [LiClO4(DETAN)] (1), was characterised by single-crystal X-ray diffraction and NMR spectroscopy.
