Abstract
The reaction of Bis[O,O-2,3;O,O-5,6(chloro carboxylic methyliden)]L-ascorbic acid with the 2-picolylamine gave new product Bis[O,O-2,3;O,O-5,6(N,N-dicarboxylic methyliden)n-2-methylene pyridyl]L-ascorbic acid (LP), which was isolated and characterized by 1 H, 13 C-NMR, elemental analysis (CHN), mass spectroscopy, UV-visible and Fourier Transform infrared (FTIR) methods. The complexes of the ligand (LP) with metal ions, M +2 = (Cu, Co, Ni, Cd , Hg and Cr +3 ) were synthesized and characterized by FTIR, UV-Visible, molar conductance, atomic absorption, magnetic susceptibility, elemental analysis (CHN) methods. The analysis showed that the ligand (LP) coordinating with metal ions through the monodentate carboxylato and amino group manner resulting in six-coordinated metal ion. The TLC for (LP) and complexes showed one spot for each indicating the purity of these compounds.
