A new unsymmetrical tetradentate Schiff base (H2L) was synthesized using 5-chloro-2-hydroxybenzophenone, o-phenylenediamine and o-vanillin. Three Ln(III) complexes of this Schiff base with the general composition [Ln(HL) (NO3)2( H2O)] ·2H2O (Ln = Er, Pr, Gd), have been prepared and characterized by elemental analyses, IR spectra, UV spectra, 1H NMR spectra, TG-DTG and molar conductance. The antibacterial activities of the ligand and its complexes are also studied. The antibacterial experiments indicate that the ligand and its complexes possess antibacterial activity against Escherichia coli, Staphylococcus aureus and Bacillus subtilis and that the complexes have higher activity than that of the Schiff base.

Two novel asymmetric salen ligands H2L1 [N-phenyl-N-(2-hydroxy-5-methylphenyl)-N'-(2-hydroxy-3-methoxylphenyl)-o-phenyldiamine] and H2L2 [N-phenyl-N-(2-hydroxy-5-chlorophenyl)-N'-(2-hydroxy-3-methoxylphenyl)-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.
