Abstract
Two new and two previously reported Schiff base ligands as well as four corresponding new Cu(II) complexes (CuL1–4) were synthesized and characterized. The Schiff base ligands were synthesized from condensation of 5-bromo-2-hydroxy-3-nitrobenzaldehyde with aliphatic (H2L1–2) or aromatic (H2L3–4) diamines. Crystal structures of CuL2 and CuL3 were determined by X-ray crystallography. Antibacterial properties of these ligands and complexes were studied against four human pathogenic bacteria. The complexes showed moderate antibacterial activities, higher than those of the ligands.
