and 13C) spectroscopy. Furthermore, the crystal structures of HL3, HL4 and C4 were analyzed by single-crystal X-ray diffraction (SC-XRD). The XRD studies revealed that C4 has 2:1 ligand-to-metal ratio and adapts highly distorted square planar geometry. The in vitro antibacterial activities of the synthesized ligands and their respective copper(II) complexes were elaborated by screening them against
