Abstract

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. The strong and broad (O-H) and (N-H) vibration of ligand at 3210 cm¹ also disappears and a new strong band appears in the complex between 3450-3540 cm¹ confirming the presence of at least one free (OH) group even in the complex molecule. The disappearance of broad and very strong band at 3210 cm³ further suggests the deprotonation of second (OH) group i.e. (N-OH) proton located at hydroxamic acid moeity.
