Abstract: In complexes (OH) amide bands (C=O) and (N-O) of ligand molecule are affected appreciable. In the basis of infra-red spectra that aldimino (azo methine group nitrogen, C=N) nitrogen and deprotonated hydroxamic part (N-O) nitrogen atoms are the bonding sites of a(p-methoxy aceto phenone) imino aceto hydroxamic acid. In case of ammine complexes, the broad band at 3300 cis attributed to (N-H) band of co-ordinated ammonia molecules in the complexes. In pyridine and picoline containing complexes the position of (C=N) band could not be ascertained difinitaly due to bulky ligand molecule and amide as well as imids group (C=N) vibrations. It is expected that one hyddroxy (OH) proton of the ligand molecule will be diprotonated forming mono-anionoc bidentate donor molecule. In this case (N-OH) proton of the hydroxamic acid moeity is lost producing uninegative ion. The resultant ligand acts as bidentate molecule which co-ordinat through imino nitrogen and one aldimino nitrogen atom of the ligand molecule. In almost all the complexes the broad hyddrogen bonded u(OH) vibration located at 2400-23-40 cm disappears suggesting the absence of hydrogen bonding in the complexes as well as the deprotonation of hydrogen bonded (OH) hydrogen.
