Abstract
A new transition metal complexes of Cu (II), Co (II) , and Ni (II) were synthesized from the Schiff base (2-Furalidene-1-phenylsemicarbazide SB) and the organophosphorus Schiff base (2-Furalidenediphenylphosphate-1-phenylsemicarbazide OPSB). The ligands were characterized from their metal analysis, IR, UV-Vis, NMR, and XRD spectral studies. The structural features of complexes were obtained by their elemental analyses, magnetic susceptibility, molar conductance, IR, UV-Vis spectral, and molar ratio studies. The data showed that these complexes have the composition of ML2 for SB ligand and ML for OPSB. According to the UV-Vis, magnetic susceptibility data the octahedral geometry was suggested for all complexes. From XRD results, the practical size of ligands and SB complexes were in the nano range with crystallinity structure. The ligands and their metal complexes have been screened for their antioxidant, antibacterial and antifungal activity.
