salts. The complexes were characterized by various spectroscopic techniques as well as single crystal X-ray structure determination. Nitric oxide reactivities of the complexes were studied in acetonitrile as well as methanol solvent. It has been found that the ligand frameworks have a considerable effect in controlling the mechanism of the reduction of a Cu(II) center by nitric oxide. The flexibility
四种 Cu( II ) 配合物1、2、3和4与配体L 1 1、L 2 2、L 3 3和L 4 4 [ L 1 1 =N 1, N 2-双((吡啶-2-基)甲基)乙烷-1,2-二胺; L 2 2 =N 1, N 3-双((吡啶-2-基)甲基)丙烷-1,3-二胺; 大号3 3 =N 1, N 1, N 2-三((吡啶-2-基)甲基)乙烷-1,2-二胺; L 4 4 = N 1-((1-甲基-1 H-咪唑-2-基)甲基) -N 1, N 2-双((吡啶-2-基)甲基)乙烷-1,2-二胺] ,分别作为它们的高氯酸盐。通过各种光谱技术以及单晶 X 射线结构测定对配合物进行了表征。研究了配合物的一氧化氮反应性乙腈也甲醇溶剂。已发现配体框架在控制一氧化氮还原Cu( II )中心的机制方面具有相当大的作用。发现在 NO 配位后,Cu( II ) 配合物的配体/s 获得三角双锥几何形状的灵活性是决定它们相互
