报道了三齿配体 N,N-二 (2 '-苯并咪唑甲基 )亚胺 (IDB)及锰 ( )单核配合物 [Mn(IDB) 2 ]Cl2 · CH3OH·H2 O( )和 [Mn(IDB) 2 ](Cl O4) 2 · CH3CH2 OH· H2 O( )的合成和表征 .依据元素分析、摩尔电导、UV- Vis和 IR分析 ,初步推测该系列配合物中 Mn( )离子可能为典型的四方锥或八面体结构 。

This paper reports the synthesis and characterstics of a tridentate ligand N,N di(2' benzimidazolyl methyl) imide (IDB) and two containing manganese (Ⅱ) mononuclear complexes [Mn(IDB) 2]Cl 2·CH 3OH·H 2O(Ⅰ),[Mn(IDB) 2](ClO 4) 2·CH 3CH 2OH·H 2O(Ⅱ).Based on the elemental analyses,molar conductivity,UV Vis,middle and far IR spectra,it is infered that coordination geometry of these two complexes may be close to a typical square pyramidal or octahedral. These two complexes are better structure models of the catalase and ribonucleotide reductase.
