•A novel diazo-coupled compound with phenylazo group at a rather unusual position.•The synthesized compound was found to be acting as a potential ligand.•Five chelates of phenylazo dehydroacetic acid were synthesized and characterized.•Analytical, spectral and thermal data confirm the structure of the compounds.
Five chelates of 3-acetyl-5-azophenyl-4-hydroxy-6-methyl-pyran-2-one (phenylazo dehydroacetic acid) with Cr(III), Fe(III), Ni(II), Cu(II) and Zn(II) have been synthesized and characterized by elemental analysis, magnetic susceptibility measurements, electronic, 1H NMR, FAB mass, IR-spectral and thermal (TG/DTG) analytical techniques. In the present work it has been found that oxygen of the deprotonated OH group and one of the azo-nitrogens of the ligand take part in coordination. The Cr(III), Fe(III) and Ni(II) complexes were found to be having octahedral geometry and the Cu(II) and Zn(II) tetrahedral.
