Synthesis and spectroscopic of some new metal ions complexes's with [N- (4-methoxy benzoyl amino)‎ -thioxo methyl] leucine

Abstract EN

A new ligand [N-(4-methoxy benzoyl amino)-thioxo methyl ] leucine (آس) was prepared from the reaction of (4-methoxy benzoyl isothiocyanate with leucine acid in molar ratio (l:l), it was characterized by elemental analysis (C.H.N.S), FT-]R, UV-Vis, *H and ^C-^MR.

The complexes of the bivalent ions (Mn, Fe, Co, Ni, Cu, Zn, Cd and Hg ) have been prepared and characterized too.

The structural was established by elemental analysis (C.H.N.S), FT-]R, UV-Vis spectra, conductivity measurements atomic absorption and magnetic susceptibility and determination of molar ration (M:L).

The complexes showed characteristic behavior of tetrahedral geometry around the metal ions except with (Cu) complex showed square planer.
