A series of neutral, 5-coordinate pyrrolyldipyrrinato Sn(IV) complexes have been synthesized via reaction of a pyrrolyldipyrrin, or its corresponding hydrochloride salt, with dibutyltin or diphenyltin oxide. The complexes are structurally unique in that all three nitrogen atoms of the pyrrolyldipyrrinato ligand bind to the tin center, making these complexes the first examples of pyrrolyldipyrrins behaving as LX(2) ligands. The complexes are highly fluorescent, exhibiting fluorescence quantum yields between 0.28 and 0.61, and display interesting preliminary biological activity.
一系列中性的、五配位的吡咯并二吡咯啉锡（IV）配合物已经通过吡咯并二吡咯啉或者其相应的盐酸盐与二丁基锡或氧化二苯锡的反应而被合成。这些配合物在结构上是独特的，因为吡咯并二吡咯啉配体的三个氮原子都与锡中心结合，这使得这些配合物成为吡咯并二吡咯啉作为 LX(2)配体的第一个例子。这些配合物具有很高的荧光性，其荧光量子产率在 0.28 到 0.61 之间，并且表现出有趣的初步生物活性。
