Abstract :
The reaction of L-ascorbic acid with the tirchloroacetic acid in the presence of
potassium hydroxide gave new product Bis[O,O-2,3;O,O-5,6(chlorocarboxylicmethyliden)]Lascorbic acid (H2L) which was isolated and characterized by 1
H,13C-NMR, elemental analysis
(C,H,N), UV-Visible and Fourier Transform Infrared (FTIR). The complexes of the ligand
(H2L) with metal ions, M+2= (Cu, Co, Ni, Cd and Hg) were synthesized and characterized by
FTIR, UV-Visible, molar conductance, atomic absorption, magnetic susceptibility and the
molar ratio. The analysis evidence showed the binding of the metal ions with (H2L) through
the bicarboxylato group manner resulting in six-coordinated metal ion. The TLC for (H2L)
and complexes showed one spot for each indicating the purity of these compounds.
