The molecular structure of the μ-nitrido dimer, μ-nitrido-bis(2,3,7,8,12,13,17,18-octaethylporphyrinato)iron, is reported. The axial Fe – N distances average to 1.657(11)Å and the equatorial distances average to 2.005(5)Å. Although not required by symmetry, the two iron centers appear equivalent and are consistent with an assignment of a low-spin state and a formal oxidation state of +3.5. A comparison of this structure with other nitrido-bridged species is given.

μ-氮化物配合物{[Fe(OEP)]2N}的结构表征

报道了μ-亚硝基二聚体μ-亚硝基-双(2,3,7,8,12,13,17,18-八乙基卟啉)铁的分子结构。轴向 Fe - N 距离平均为 1.657(11)Å，赤道距离平均为 2.005(5)Å。尽管对称性不需要，但两个铁中心看起来是等效的，并且与低自旋态和 +3.5 的正式氧化态的分配一致。给出了这种结构与其他氮化物桥接物种的比较。
