The reaction of acetohydroxamic (CH3C(O)-NHOH), benzhydroxamic acid (PhC(O)-NHOH) or 1-hydroxypyridin-2(1H)-one (pyrC(O)-NOH) in the presence of tris-(2-pyridylmethyl)amine (TPA), sodium methoxide and an iron(III) salt yields the mononuclear complexes [Fe(TPA)(CH3C(O)-NHO)]2+ (), [Fe(TPA)(PhC(O)-NHO)]2+ () and [Fe(TPA)(pyrC(O)-NO)]2+ (). The hydroxamato complexes and are easily converted to their hydroximato form [Fe(TPA)(CH3C(O)=NO)]+ () and [Fe(TPA)(PhC(O)=NO)]+ () by addition of base. The complexes described were characterized by UV-vis spectroscopy, EPR and cyclic voltammetry, as well as single-crystal X-ray crystallography for and .
在三（2 - 吡啶甲基）胺（TPA）、甲醇钠和铁（III）盐存在的情况下，乙酰氧肟酸（CH₃C(O)-NHOH）、苯甲羟肟酸（PhC(O)-NHOH）或1 - 羟基吡啶 - 2(1H)-酮（pyrC(O)-NOH）反应生成单核配合物[Fe(TPA)(CH₃C(O)-NHO)]²⁺（）、[Fe(TPA)(PhC(O)-NHO)]²⁺（）和[Fe(TPA)(pyrC(O)-NO)]²⁺（）。通过加入碱，异羟肟酸配合物和很容易转化为它们的羟胺形式[Fe(TPA)(CH₃C(O)=NO)]⁺（）和[Fe(TPA)(PhC(O)=NO)]⁺（）。所描述的配合物通过紫外可见光谱、电子顺磁共振和循环伏安法进行了表征，以及对和进行了单晶X射线晶体学分析。
