Azo fuctionalised Schiff base ligands having N₂O₂ donor binding sites are capable of forming metal complexes and can be used as potential plant micronutrient supplier. Two different ligands and their copper complexes were synthesised by conventional protocols and then characterised by both spectroscopic and elemental analysis. Investigations were done by taking rice seeds as plant material. Various growth and biochemical parameters were monitored by taking different concentrations of CuSO₄, prepared ligands and their Cu(II) complexes. Analysis of various biochemical results reveal that Schiff base Cu(II) complexes have less toxic effects than copper sulphate on rice seedlings and thus facilitates better tolerance to copper toxicity than copper sulphate.
