Chemical switching behaviour of tricarbonylrhenium(I) complexes of a new redox active 'Pincer' ligand

摘要

The structures and optoelectronic properties of tricarbonyl-- rhenium(I) complexes of di(2-pyrazolyl-p-tolyl)amine in its neutral and deprotonated (uninegative amido) form were investigated. Reactions of the complexes with Bronsted acids or bases result in distinctive changes of colour and electrochemical activity owing to the non-innocent nature of the ligand.
