Synthesis, Electronic Spectral Study and Antifungal Evaluation of Mixed Ligand Complexes of Dibasic Tridentate Schiff Base and Naphthoic Acid with Transition Metal Ions

Transition metal complexes of Mn(II), Co(II) and Cu(II) with dibasic tridentate Schiff base derived from the condensation of thiosemi-carbazide with acetoacetanilide as primary ligand and 1-hydroxy-2-naphthoic acid as co-ligand have been synthesized. The mixed ligand complexes of the above mentioned metal ions were characterized by analytical, magnetic and electronic spectral study. The transition metal complexes were also evaluated for antifungal activity against Drechslera tetramera, Fusarium oxysporum and Aternaria alternata at different concentrations.
