Synthesis and characterization of schiff base ligand derived from o-phenylenediamine and 4-nitrobenzaldehyde and its complexes / Siti Rohayu Ab. Malik

The Schiff base ligand was prepared by a condensation reaction of o-phenylenediamine with 4-nitrobenzaldehyde. Metal complexes of a Schiff base were derived from condensation of o-phenylenediamine and 4-nitrobenzaldehyde in the presence of metal salt namely Ni(II) acetate tetrahydrate, Mn(II) nitrate tetrahydrate, Co(II) acetate, as well as Cu(II) chloride. The ligand and its metal complexes are reported and characterized based on elemental analysis, IR spectroscopy and molar conductance. All the metal complexes were non-electrolyte.
