Three iron(II)-2-aminophenolate complexes [(L1)FeII(4-tBu-HAP)] (2), [(L1)FeII(HAP)] (3), and [(L1)FeII(4-NO2-HAP)] (4) [L1 = tris(2-pyridylthio)methanido anion, 4-tBu-HAP = 2-amino-4-tert-butylphenolate, HAP = 2-aminophenolate, and 4-NO2-HAP = 2-amino-4-nitrophenolate] were isolated and characterized to study their reactivity towards dioxygen. The complexes were synthesized from the iron(II)-acetonitrile
三种铁 (II)-2-氨基苯酚络合物 [(L1)FeII(4-tBu-HAP)] (2)、[(L1)FeII(HAP)] (3) 和 [(L1)FeII(4-NO2) -HAP)] (4) [L1 = tris(2-pyridylthio)methanido 阴离子,4-tBu-HAP = 2-amino-4-tert-butylphenolate,HAP = 2-aminophenolate,和 4-NO2-HAP = 2-氨基-4-硝基苯酚]被分离并表征以研究它们对分子氧的反应性。这些配合物是由铁 (II)-乙腈配合物 [(L1)FeII(CH3CN)2]+(1) 使用取代的 2-氨基苯酚盐合成的。4 的单晶结构表明单核中心铁原子由四齿 N3C 配体和单阴离子双齿 4-NO2-HAP 配位,从而产生扭曲的八面体配位排列。六配位铁 (II) 配合物 2 和 4 与分子氧反应形成相应的铁
