Synthesis and Characterization of Mn(Ⅲ) Chloro Complexes with Salen-Type Ligands

Aseries of novel salen-type complexes {[Mn(III)($L_{acn}$)CI]: n=1~11} containing CI- ion were obtained by reactions of the Mn(CH$_3$COO)$_2$�� 4H$_2$O with the potentially tetradentate compartmental ligand {$H$_2$L_{acn}$} prepared by condensation the of one mole of diamine {ethylenediamine, 1,3-propnediamine, o-phenylenediamine and 2,2-dimethyl-1,3-propanediamine} with two moles of aldehyde {alicylaldehyde, 5-chloro-salicylaldehyde, 3,5-dichlorosalicylaldethyde, and 3,5-di-tert-butyl-2-hydroxy-benzaldehyde} in a methanol solution. The resulting salen-type lignds and their Mn(III) complexes were identified and characterized by elemental analysis, conductivity, themogravimetry and UV-VIS, IR and NMR spectroscopy.
