由于其金属配合物的稳定性、结晶度和光谱特性，二吡咯烯是形成超分子组装体的有吸引力的配体。本文报道了两种二吡啶铁（III）配合物的合成、结构、光谱和电化学。用x射线晶体学方法获得了Fe(dipyrrrin)(3)和Fe(dipyrrinCO(2)CH(3))(3)这两种配合物的高质量结构数据。研究了这两种配合物的紫外-可见吸收光谱，并对配合物进行了循环伏安实验来评价铁（III/II）对。这代表了铁-二吡啶配合物的第一个结构，以及任何介位取代的二吡啶过渡金属配合物的第一个电化学研究。(C) 2002 Elsevier Science B.V.版权所有
Dipyrromethenes (dipyrrins) are attractive ligands for forming supramolecular assemblies due to the stability, crystallinity, and spectroscopic properties of their metal complexes. Herein we report the synthesis, structure, spectroscopy, and electrochemistry of two dipyrrin iron(III) complexes. High-quality structural data of both complexes, Fe(dipyrrin)(3) and Fe(dipyrrinCO(2)CH(3))(3), have been obtained by X-ray crystallography. The UV-Vis absorption spectrum of both complexes has been examined and cyclic voltammetry experiments have been performed on the complexes to evaluate the iron(III/II) couples. These represent the first structures of iron-dipyrrin complexes, as well as the first electrochemical studies of any meso-substituted dipyrrin transition metal complexes.
