Novel organophosphorus Schiff base ligands: Synthesis, characterization, ligational aspects, XRD and biological activity studies
Six complexes have been synthesized from Cu(II), Ni(II), and Co(II) with new bidentate N2 donor Schiff base ligand (2-methoxybenzalidene-1-phenylsemicarbazide L1) and tridentate N2O donor organophosphorus Schiff base ligand (2-methoxybenzalidenediphenylphosphate-1-phenylsemicarbazide L2). Both ligan...

| Summary: | Six complexes have been synthesized from Cu(II), Ni(II), and Co(II) with new bidentate N2 donor Schiff base ligand (2-methoxybenzalidene-1-phenylsemicarbazide L1) and tridentate N2O donor organophosphorus Schiff base ligand (2-methoxybenzalidenediphenylphosphate-1-phenylsemicarbazide L2). Both ligands were synthesized and characterized by metal analysis, infrared (IR), ultraviolet visible (UV-Vis), and nuclear magnetic resonance (NMR) spectral studies. The chemical structures of the synthesized complexes were characterized using their metal analysis, magnetic susceptibility, molar conductance, IR, and UV-Vis spectra. According to molar ratio studies, the complexes have the composition of ML2 for L1 and ML for L2. The X-ray diffraction (XRD) studies showed that the particle size of ligands and L1 complexes were in nano-range. The ligands and their metal complexes have been screened for their antioxidant, antibacterial and antifungal activity. |
