The complex compounds of pyridine-3-carboxylic acid hydroxymethyl amide, LH with Ni (II), Cu (II), Fe (II) and Cr (II) have been isolated and characterized on the basis of their elemental analysis through IR magnetic and electronic studies. The ligand has been found to possess the tridentate character and the presence of intrahydrogen bonding in it is evidenced from the IR spectral study. It form complexes with Cu (II) and Cr (III) after losing one proton (H+) from its imidolic form at pH 8 but no proton is lost in the Ni (II) and Fe (II)- complexes at Ph=6. They all are tetrahedral except the Cu (II)-complex, which is square planar. They all are paramagnetic.
