Abstract :
The Schiff base derived from o-tosylaminobenzaldehyde and p-aminoazobenzene and its metal chelates (Co2+, Ni2+, Cu2+, and Zn2+) have been synthesized and investigated (IR, 1H NMR, XANES, EXAFS spectroscopy, X-ray diffraction, magnetic measurements). It was found that the azomethine exists in the amino-imine tautomeric form both in solutions and solid state. XAFS investigations reveal that the complexes adopt either distorted tetrahedral or octahedral (due to additional coordination of oxygen atoms of the tosylamino group) ligand environment.
