2‑Pyrrolyloximes in High-Nuclearity Transition-Metal Cluster Chemistry: Fe10 and Fe12

The employment of 2-pyrrolyloximes in high-nuclearity transition-metal cluster chemistry has provided access to unprecedented decanuclear and dodecanuclear FeIII cagelike clusters bearing the anion of pyrrole-2-carboxaldehyde oxime (praoH2), the simplest member of this new family of ligands; the identity of the products depends on the nature of the counteranion present in the starting materials.

将2-吡咯肟（2-pyrrolyloximes）应用于高核过渡金属团簇化学领域，成功获得了前所未有的十核与十二核三价铁（FeIII）笼状团簇，该类团簇负载有吡咯-2-甲醛肟（pyrrole-2-carboxaldehyde oxime, praoH₂）的阴离子，而吡咯-2-甲醛肟是该新型配体家族中最简单的一员；产物的结构与组成取决于起始原料中所含反阴离子的性质。
