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

الملخص

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.
