Abstract
The two Schiff base ligands, H3L1 (02NO) and H2L2 (02N), were prepared by the condensation of o
acetoacetylphenol with either ethanolamine or ethylamine, respectively, in the molar ratio 1:1.
Both ligands contain a ketonic group, an imine group of the Schiff base linkage
1
besides a phenolic group. In addition, ligand H3L
contained a
tennenal alcoholic group. The reactions of the two ligands with Cu(ll), Ni(II), Co(II), Mn(II),
VO(IV), U02(VI), Fe(III)
and Cr(III) ions yielded solid complexes. LiOH was added in
some reactions, as a deprotonating agent The ligand H3L1 behaved as bi-, ter-, or tetradentate and
either as a morio-, or dianionic and yielded either mono-, bi-, tri-, or tetranuclear
2
metal· complexes. The ligand H2L
behaved as bi-, or
terdentate and either as a mono- or dianionic and yielded either mono- or binuclear metal
complexes. The complexes attained different geometrical structures, e.g. Cu(II) complexes are
square-planar; Ni(II), Co(II), Mn(II); Fe(III) and Cr(III) complexes are octahedral; U02(VI)
complexes are pentagonal bipyramid and VO(IV) is square pyramid. Iron (III) complexes contain
two chlorine bridges between the two Fe
(III) ions coordinated to the outer sites of two ligand molecules. chromium complex of ligand H2L2
contained two hydroxo bridges between the two Cr(III) ions coordinated to the available sites of
two ligand molecules.
