2, 2& #039, - (1- (3, 4-bis (carboxydichloromethoxy) -5-oxo-2, 5-dihydrofuran-2-yl) ethane-1, 2-diyl) bis (oxy) bis (2, 2-dichloroacetic acid) a derivative of L-ascorbic acid was prepared by reaction of L-ascorbic acid with trichloroacetic acid (14) ratio, in the presence of potassium hydroxide. A series of new metal complexes of this ligand were prepared by a reaction with the chlorides of Cd (II), Co (II), Ni (II), Cu (II) and Zn (II). The new ligand and its complexes were identified by C. H. N. , IR, UV-visible spectra, Thermogravimetric analysis (TGA), as well as 1H, 13C-NMR and Mass spectra for ligand L. The complexes were also identified by molar conductance, atomic absorption, magnetic susceptibility and X-ray diffraction for Cu (II) complex. FT-IR spectra of complexes suggest coordination occurs through the (COO-) as a bidentates bonding mood. Elemental analyses of the all complexes suggest that the metal to ligand ratio is 21. The complexes were expected to be octahedral geometry. Antibacterial activity of the L and complexes were tested against different kinds of bacteria.
