Spectral and thermal characterization of 3-acetyl-5-azophenyl-4-hydroxy-6-methyl-pyran-2-one and its metal complexes
摘要:
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, H-1 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. (c) 2013 Elsevier B.V. All rights reserved.
