Na2L1. The two complexes have been characterized by single-crystal X-ray diffraction, magnetic susceptibility, EPR spectroscopy, and electrochemistry. X-Ray crystallography revealed that 1 is a manganese(II) hexamer and 2 is a manganese(II) dimer featuring an unprecedented mono-μ-acetato, mono-μ-chlorido bridging motif. The ability of the complexes to catalyse H2O2 disproportionation, thereby acting
在这项工作中,我们报告了两种小说的综合 锰[ L1 3 Mn II 6 ](ClO 4)6(1 ·(ClO 4)6)和[ L2 Mn II 2(μ-OAc)(μ-Cl)](ClO 4)2(2 ·(ClO 4)2),其中L1 2−是2,2'-(1,3-亚苯基双(亚甲基))双((2-(双(吡啶-2-基甲基)氨基)乙基)氮杂二基)二乙酸阴离子和L2为N1,N1 '-(1,3-亚苯基双(亚甲基))双(N2,N2'-双(吡啶-2-基甲基)乙烷-1,2-二胺)。Na 2 L1和L2配体建立在同一骨架上,L2仅包含氮供体,而两个羧酸盐在Na 2 L1中引入了武器。两种配合物的特征在于单晶X射线衍射,磁化率,EPR光谱和电化学。X射线晶体学分析表明1是锰(II)六聚体,2是一个锰(II) 具有史无前例的二聚体 单-乙酸, 单μ氯桥接主题。络合物催化H 2 O 2歧化的能力,从而充当模型锰 过氧化氢酶,已经
