Complexation of iron(III) with the heterodonor chelating agent 3,5-di-tert-butylsalicylidene benzoylhydrazine, H2(3,5-tBu2)salbh, in the absence or presence of a base affords the complex cation [Fe{H(3,5-tBu2)salbh}2]+ or the neutral compound [Fe{H(3,5-tBu2)salbh}{(3,5-tBu2)salbh}], respectively, as revealed by single-crystal X-ray analyses. Such a synthetic and crystallographic demonstration of the coordination versatility of an aroylhydrazone toward iron is uncommon. The oxidation and spin states of the iron have been verified with magnetic and spectroscopic measurements.
在不存在或存在碱的情况下，铁（III）与杂供体螯合剂3,5-二叔丁基水杨酰苯甲酰肼（H2(3,5-tBu2)salbh）络合，分别得到络合阳离子[Fe{H(3,5-tBu2)salbh}2]+或中性化合物[Fe{H(3,5-tBu2)salbh}{(3,5-tBu2)salbh}]，单晶X射线分析表明了这一点。芳酰腙对铁配位多样性的这种合成和晶体学证明并不常见。铁的氧化态和自旋态已通过磁性和光谱测量得到验证。
