Three copper(II) complexes with bidentate ligands L1, L2 and L3 [L1, N,N/-dimethylethylenediamine; L2, N,N/-diethylethylenediamine and L3, N,N/-diisobutylethylenediamine], respectively, were synthesized as their perchlorate salts. The single crystal structures for all the complexes were determined. The nitric oxide reactivity of the complexes was studied in acetonitrile solvent. The formation of thermally
具有双齿配体L 1,L 2和L 3 [ L 1,N,N /-二甲基乙二胺的三个铜(II)配合物;分别合成了L 2,N,N,N /-二乙基乙二胺和L 3,N,N,N /-二异丁基乙二胺。确定了所有配合物的单晶结构。配合物的一氧化氮反应性进行了研究。乙腈溶剂。热不稳定[形成Cu II -NO]与在乙腈中的溶液的一氧化氮的复合物的反应中间体中观察到铜(还原之前II)中心铜(我)。发现减少是由于在配体的仲胺位点同时发生亚硝基化。分离并表征了所有亚硝化产物。发现单亚硝化产物和二亚硝化产物的产率之比取决于存在于配体骨架中的N-取代。
