we describe the synthesis, characterization, and stability studies of new FeII complexes prepared with the ligand N,N′-dimethyl-N,N′-bis(4-nitropyridin-2-ylmethyl)ethane-1,2-diamine (L42NO2). The properties of these complexes were probed by magnetic, spectroscopic, and electrochemical techniques and compared with those of the parent complexes prepared with the unsubstituted ligand N,N′-dimethyl-N,
在本文中,我们描述了用配体N,N'-二甲基-N,N'-双(4-硝基吡啶-2-基甲基)乙烷-1,2制备的新型Fe II配合物的合成,表征和稳定性研究。-二胺(L 4 2 NO 2)。这些配合物的性质通过磁性,光谱和电化学技术进行探测,并与用未取代的配体N,N'-二甲基-N,N'-双(吡啶-2-基甲基)乙烷-制备的母体配合物进行比较。1,2-二胺(BPMEN或L 4 2)。这对与π接受硝基吡啶基团的官能化增加了配位场的强度和金属中心的,而不改变复合物的稳定性的路易斯酸性。
