A rare, low-spin Fe(IV) imide complex [(pyrr2py)Fe=NAd] (pyrr2 py(2-) = bis(pyrrolyl)pyridine; Ad = 1-adamantyl) confined to a cis-divacant octahedral geometry, was prepared by reduction of N3Ad by the Fe(II) precursor [(pyrr2py)Fe(OEt2)]. The imide complex is low-spin with temperature-independent paramagnetism. In comparison to an authentic Fe(III) complex, such as [(pyrr2py)FeCl], the pyrr2py(2-) ligand is virtually redox innocent.
一种罕见的低自旋 Fe(IV)酰亚胺配合物[(pyrr2py)Fe=NAd]（pyrr2py(2-) = 双（吡咯基）吡啶；Ad = 1-金刚烷基）被限制在顺式缺八面体几何构型中，通过 Fe(II)前体[(pyrr2py)Fe(OEt2)]还原 N3Ad 制备。酰亚胺配合物是低自旋的，具有温度无关的顺磁性。与真实的 Fe(III)配合物（如[(pyrr2py)FeCl]）相比，pyrr2py(2-)配体几乎没有氧化还原活性。
