Two novel asymmetric salen ligands H 2 L 1 [ N ‐phenyl‐ N ‐(2‐hydroxy‐5‐methylphenyl)‐ N′ ‐(2‐hydroxy‐3‐meth‐ oxylphenyl)‐ o ‐phenyldiamine] and H 2 L 2 [ N ‐phenyl‐ N ‐(2‐hydroxy‐5‐chlorophenyl)‐ N′ ‐(2‐hydroxy‐3‐methoxyl‐ phenyl)‐ o ‐phenyldiamine] and their metal complexes ML n (M=Zn, Co, Ni, Cu; n =1, 2) have been prepared and characterized by elemental analyses, 1 H NMR, ESI‐MS, FT‐IR and UV‐Vis spectra. In particular, the complex ZnL 1 , the binuclear monosalphen complex, was synthesized and studied in detail using 1 H NMR and ESI‐MS techniques. For other metal complexes under the same reaction conditions, only mononuclear complexes were obtained. The results are relevant to both the metal ions and the structure of ligands.
