Synthesis, Spectroscopic Characterization, and Crystal Structure of a Mononuclear Mn(II) Complex Derived from the N'-(4-hydroxy-3-methoxybenzylidene) Isonicotinohydrazide Ligand: Evaluation of the Antioxidant Activity of the Ligand and Its Complex
A mononuclear manganese(II) complex of N′-(4-hydroxy-3-methoxybenzylidene)isonicotinohydrazide (H₂L) was synthesised and characterised to examine its structural features and DPPH radical-scavenging activity relative to the free ligand. The ligand was prepared by condensation of isonicotinic acid hydrazide with para-van...
