Abstract
Abstract In the present work, a series of new Schiff base ligands from acetylacetone and salicylaldehyde with sulfonamides derivatives were synthesized and characterized by spectral and analytical techniques. The molecular structures of ligands, N-({4-[(E)-(2-hydroxybenzylidene)amino]phenyl}sulfonyle)acetamide (HL1), N-({4-[(E)-(2-hydroxybenxiliden)amino]phenyl}sulfonyle)benzamide (HL2) and 4-((4-oxopentan-2ylidene)amino)benzenesulfonamide (HL3) were also determined by the method of X-ray diffraction. Also, new copper(II) complexes [CuLx](x = 1 for 1, x = 2 for 2, x = 3 for 3) constructed from HLx were synthesized and characterized by FT-IR, UV–vis spectroscopy and XRD. The copper(II) complexes were screened for their antimicrobial activities against the selected bacteria and compared to the free ligands, using the disc diffusion method.
