Bioactive Mixed Ligand Metal Complexes Of Cu(II), Ni(II), And Zn(II) Ions: Synthesis, Characterization, Antimicrobial And Antioxidant Properties

ABSTRACT A series of transition metal complexes having general formula [M(L1)(L2)](NO3)2, (where, M = Cu(II), Ni(II), and Zn(II)) of mixed ligands, L1 = Isonicotinamido-Thiophene-2-Carbaldimine, L2 = 1, 10-phenanthroline, were synthesized. The obtained compounds were successfully characterized by di...
