Abstract |
|
|
A
series of new aluminum(III), gallium(III), indium(III) and thallium(III) complexes with three
tridentate Schiff base of 2-(3-hydroxy-1-methyl-but-2-enylideneamino)phenol [H2L1], 2-(3-hydroxy-1-phenyl-but-2-enylideneamino)phenol
[H2L2] and
(2Z)-2-((Z)-1,1,1-trifluoro-4-hydroxypent-3-en-2-ylideneamino)phenol [H2L3]
(which have been derived from 2-aminophenol and diketones
of acetylacetone, benzoylaceton
and 1,1,1-trifluoro -2,4-pentadion) with the general formula [Y][ML2]
(M = Al3+, Ga3+, In3+, Tl3+ and Y
=Et3NH+) were synthesized and characterized by elemental
analysis, 1H NMR, FT-IR, UV–Vis spectrophotometry
and mass spectroscopy. The thermodynamic formation constants of the complexes
were determined spectrophotometrically at 25 °C in
methanol. The trend of formation constants of the complexes are as follow:
Al3+
< Ga3+ < In3+ < Tl3+
H2L1
> H2L2 > H2L3
