Preparation of new transition and non-transition metals complexes with N-acetylglucose amine (NAGA)‎

الملخص EN

New transition and non-transition metals complexes were prepared by coordination of Mn(II) with each of Zn(II), Cd(II) and Hg(II) metals and Fe(II)with each of Zn(II) , Cd(II) and Hg(II) with the ligand L = N-acetylglucose amine(NAGA) in 1:1:4 molar ratio.

The metal ions were tridentate bonded to the ligand in the complexes.

Complexes have been synthesized by three routes, conventional direct reaction in neutral medium and by microwave and altrasoud irradiation to give complexes of the general formula [MM / (NAGA)4] Cl4.

The percentage yield were (50-60, 80-90 and > 95 and the reaction time (300, 5, 120 minutes respectively) of the first, second and third routes.

Physical measurements including IR and UV / Visible spectra, CHN analysis and molar conductivity measurements showed octahedral geometry around the metals.

This geometry (three dimensional structure) of complex (i) as representative of these complexes at minimized energy was established by chem.3D Ultra ; molecular modeling and analysis confirmed the suggested structure.
