Abstract
I’
This thesis comprises three chapters. The first one deals with a general
literature review on the coordination chemistry of acylhydrazones. The aim of
investigation and statement of the problem are also included in this chapter which
ended with a general review on the basic concepts of magneto chemistry.
The second chapter is devoted to a detailed discussion of the results obtained
throughout the work and contains two main parts. The first part deals with the
synthesis and characterization of some copper(ll) complexes derived from (mono-, di-
and poly) hydrazone oximes. Diacetylmonoxime was allowed to react with
monoacylhydrazines NH2NHCOR (R = CH3, C6Hs), dicarboxylic acid dihydrazides
NH2NHCO(CH2)nCONHNH2 (n = 0, 1, 2, 3 and 4) and poly(a.-methylacrylic acid
hydrazide) to give respectively, mono-, di- and polyhydrazone oximes. These ligands
were characterized by elemental analysis, mass spectra and infrared as well as IH nmr
spectral techniques.
The reaction of mono- and dihydrazone oximes and their corresponding
polymeric hydrazone oximes, (2.8), (2.9) and (2.10) respectively, with copper(ll) salts
have been studied and the isolated copper(II) complexes were characterized by
elemental analysis, infrared, ultraviolet and visible spectra as well as magnetic
susceptibility measurements at different temperatures. The infrared spectral data of
the mono- and dihydrazone oximes and their corresponding copper(ll) complexes
suggest that, the hydrazone oxime ligand can act as neutral NNO tridentate ligand and
coordinate to the central copper(II) ion via the azomethine nitrogen atoms of both
hydrazine and oxime groups and keto amide oxygen as in (2.14) and (2. 19).or it can
act as a mononegative ONO or NNO tridentate ligand where coordination to the
central copper(ll) ion occurs via the azomethine nitrogen of the hydrazine group, keto
amide oxygen and the deprotonated oxime group as in (2.18) or via the azomethine
nitrogen atoms of both hydrazine and oxime groups and the deprotonated enolized
oxygen as in (2.15). The ligand can also act as a dinegative NNO tridentate ligand as
in (2.13) and (2.16) where both the oxime and carbonyl groups were enolized. The
infrared spectra of the polymeric hydrazone oxime ligand (2.10) and their copper(IJ)
metallopolymers (2.20a) were also recorded and compared with those of low
