Popis:	Two novel asymmetric salen ligands H2L1 [N-phenyl-N-(2-hydroxy-5-methylphenyl)-N′-(2-hydroxy-3-meth- oxylphenyl)-o-phenyldiamine] and H2L2 [N-phenyl-N-(2-hydroxy-5-chlorophenyl)-N′-(2-hydroxy-3-methoxyl- phenyl)-o-phenyldiamine] and their metal complexes MLn (M=Zn, Co, Ni, Cu; n=1, 2) have been prepared and characterized by elemental analyses, 1H NMR, ESI-MS, FT-IR and UV-Vis spectra. In particular, the complex ZnL1, the binuclear monosalphen complex, was synthesized and studied in detail using 1H 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.
