利用位阻Ar-nacnac配体（Ar-nacnac =[（2,6-二异丙基苯基）NC(Me)]2CH的阴离子）制备了几种Fe和Co的亚硝基配合物。二硝基铁配合物[Fe(NO)2(Ar-nacnac)](1)和（Bu4N）[Fe(NO)2(Ar-nacnac)](2)与[FeIII(TPP)Cl] （TPP =四苯基卟啉dianion）反应生成[FeII(TPP)(NO)]和相应的单硝基铁配合物。我们评估了影响NO与dics 1和2转移的因素，以及相关的单硝基铁配合物[Fe(NO)Br(Ar-nacnac)]， 4的化学性质。讨论了相关的二硝基钴[Co(NO)2(Ar-nacnac)]， 3的合成及其性能，并与dics 1和2进行了比较。用x射线晶体学测定了其中几种化合物的固态结构。
Several nitrosyl complexes of Fe and Co have been prepared using the sterically hindered Ar-nacnac ligand (Ar-nacnac = anion of [(2,6-diisopropylphenyl)NC(Me)]2CH). The dinitrosyl iron complexes, [Fe(NO)2(Ar-nacnac)] (1) and (Bu4N)[Fe(NO)2(Ar-nacnac)] (2) react with [FeIII(TPP)Cl] (TPP = tetraphenylporphine dianion) to generate [FeII(TPP)(NO)] and the corresponding mononitrosyl iron complexes. The factors governing NO-transfer with DNICs 1 and 2 are evaluated, together with the chemistry of the related mononitrosyl iron complex, [Fe(NO)Br(Ar-nacnac)], 4. The synthesis and properties of the related cobalt dinitrosyl [Co(NO)2(Ar-nacnac)], 3, is also discussed for comparison to DNICs 1 and 2. The solid-state structures of several of these compounds as determined by X-ray crystallography are reported.
