The reaction of bis[O,O-2,3;O,O-5,6-(chloro(carboxylic)methylidene)]-L-ascorbic acid with the 2-picolylamine gave new product bis[O,O2,3;O,O-5,6-(N,N-dicarboxylicmethylidene)-N-2-methylenepyridyl]-L-ascorbic acid (LP), which was isolated and characterized by 1H,13CNMR, elemental analysis (CHN), mass spectroscopy, UV-visible and Fourier Transform infrared (FTIR) methods. The complexes of LP
with metal ions, M2+ (Cu, Co, Ni, Cd, Hg) and Cr3+ were synthesized and characterized by FTIR, UV-Visible, molar conductance, atomic
absorption, magnetic susceptibility, elemental analysis (CHN) methods. The analysis showed that the ligand coordinates with metal ions
through the monodentate carboxylato and amino group resulting in six-coordinated metal ion complexes. The TLC for LP and complexes
showed one spot for each, indicating the purity of these compounds.
Key words: Synthesis, bis[O,O-2,3;O,O-5,6-(N,N-dicarboxylicmethylidene)-N-2-methylene pyridyl]-L-ascorbic acid, metal complexes;
