Abstract
The entitled thesis ”Physico-chemical studies on some
”amino alcohol complexes” comprises three chapters.
Chapter I include a general published literature survey on
the structural chemistry and the applications of ethanolamine
complexes.
Chapter II includes the experimental part of the thesis. CrIII,
Mnll COIl NiII CUll Znll CdII Hgll and DO Il_ amino alcohol
, , , , ” 2
complexes were prepared and analyzed. The simple complexes
were separated in 1: 1, 1 :2, 2:2, 2:3 and 1:3 Metal: ligand ratios.
Heteronuclear monoethanolamine complexes are also prepared
and analyzed. Both Co-Cu-MEA and Ni-Cu-MEA complexes
were separated in 1 :2:2 ratio, while the Co-Ni-MEA complex was
separated in 1: 1:2 ratio. Different standardized instruments were
used for obtaining the required data (uv-vis., ir, magnetic
susceptibility, esr, thermal and electrical conductivity and
dielectric measurements). Some statistical studies were done to
obtain the different correlation coefficients between the data.
Chapter III is concerned for the results and discussion. In all
complexes, both oxygen and nitrogen atoms of the three ligands
(MEA-monoethanolamine; DEA-diethanolamine; TEA-triethanol-
amine) are the active centers for complexation.
The prepared CrIII and Mnll complexes are: [Cr(MEA)3]CI3,
[Cr(DEA)3]C13, [Cr(TEA)3]C13, [Mn(MEA)3]C12, [Mn(DEA)3]C12
and [Mn(TEA)3]C12 with Oh structure. All of these are of high
spin nature.
