Crystal structure of a carborane endo/exo-dianion and its use in the synthesis of ditopic ligands for supramolecular frameworks†
Abstract
The crystal structure of the deprotonated monocarba-closo-dodecaborate [12-CN-CB11H11]ā is reported. This dianion, featuring a delocalized endohedral negative charge and an exo-cluster Cā[Li] moiety, was used for the synthesis of ditopic ligands with the potential to form novel supramolecular frameworks.
