  Abstract

Cl-이온을 포함하는 일련의 salen형 착물 {[Mn(Ⅲ)(acn)Cl]: n=1∼11} 들은 Mn(C3COO2·420와 네자리 칸막이 리간드{2acn}로부터 얻었다. 이 salen형 리간드는 diamine류 {ethylenediamine, 1,3-propane diamine, 2,2-dimethyl-1,3-propanediamine, o-phenylenediamine}와 aldehyde류 {salicylaldehyde,5-chloro salicylaldehyde, 3,5-dichlorosalicylaldehyde, 3,5-di-tert-butyl-2-hydroxybenzaldehyde}를 methanol용액에서 축합반응시켜 합성하였다. 이들 리간드 및 착물들은 원소분석, 전도도, 열분석법 및 UV-VIS, IR, NMR 분광학법 등을 이용하여 확인·고찰하였다. A series of novel salen-type complexes {[Mn(Ⅲ)(acn)Cl]: n=1~11} containing Cl- ion were obtained by reactions of the Mn(C3COO2 ·42O with the potentially tetradentate compartmental ligand {2acn}, prepared by condensation the of one mole of diamine {ethylenediamine, 1,3-propanediamine, o-phenylenediamine, and 2,2-dimethyl-1,3-propanediamine} with two moles of aldehyde {salicylaldehyde, 5-chloro- salicylaldehyde, 3,5-dichlorosalicylal-dehyde, and 3,5-di-tert-butyl-2-hydroxy-benzaldehyde} in a methanol solution. The resulting salen-type ligands and their Mn(Ⅲ) complexes were identified and characterized by elemental analysis, conductivity, thermogravimetry and UV-VIS, IR, and NMR spectroscopy.
