Our successful synthesis of the first examples of Sn(IV) complexes of meso-aryl dipyrrins is reported. Sn(IV) dipyrrins are synthesized by treating meso-aryl dipyrrins with readily available SnCl2·2H2O in pyridine at reflux temperature and isolated as pure complexes by recrystallization. The X-ray structure revealed that the complex is hexa-coordinated and the Sn(IV) ion is coordinated to two dipyrrin units and two chlorides with overall appearance of a butterfly like structure. The complexes are stable in solution and characterized by spectral and electrochemical techniques.
我们成功合成了首例锡（IV）配合物的中-芳基二吡咯。锡（IV）二吡咯是通过在回流温度下用易得的 SnCl2·2H2O 处理中-芳基二吡咯，在吡啶中合成的，并通过重结晶作为纯配合物分离。X 射线结构表明，该配合物是六配位的，锡（IV）离子与两个二吡咯单元和两个氯化物配位，整体呈现出蝴蝶状结构。该配合物在溶液中稳定，并通过光谱和电化学技术进行了表征。
