Abstract

Nickel(II), palladium(II), and platinum(II) complexes of meso-aryl-substituted [26]hexaphyrin have been prepared and structurally characterized. In mono-metalated complexes, the metal ion is commonly bound with three pyrrolic nitrogen atoms and one pyrrolic beta-carbon, whereas a bis-Pd(II) complex exhibits a unique structure involving a Pd-C(alpha) bond. These results reveal novel coordination abilities of the hexaphyrin that lead to a metal-carbon bond at either pyrrolic C(beta) or C(alpha) position.

摘要

已制备并对中位芳基取代的[26]六卟啉的镍（II）、钯（II）和铂（II）配合物进行了结构表征。在单金属化配合物中，金属离子通常与三个吡咯氮原子和一个吡咯β-碳结合，而双钯（II）配合物表现出一种独特的结构，涉及一个钯-碳（α）键。这些结果揭示了六卟啉的新型配位能力，这种能力导致在吡咯C（β）或C（α）位置形成金属-碳键。
