« Expanding the Scope of Al(III) Chemistry with Ligand-Based Electron and Proton Transfer Reactions »

Le mercredi 24 Avril 2019, à 11h00, salle 774 du bâtiment Lavoisier





Louise is an inorganic and coordination chemist (http://chemgroups.ucdavis.edu/~berben/louise.html) and also an associate editor at Chem Soc Rev.

Seminar Abstract

I will talk about octahedral complexes of Al, Ga, and In(III) that each contain two bis(imino)pyridine (I2P) ligands and have the form [(I2P)2M]n, where M = Al(III), Ga(III), or In(III), and n spans 3- up to 2+ depending on the charge of each I2P ligand. The charge series can be accessed using cyclic voltammetry or chemically isolated. Mixed-valency spanning Class II partially delocalised thgouth Class II/III and Class III fully delocalised is accessed at different charge states of the ligands and with variation in the metal site. Electron delocalization will also be discussed in the context of stabilization of unusual square planar geometries for Al complexes, and in the context of the chemical reactivity that can be accessed via ligand-based electron and proton transfer reactions. Electron delocalization will also be discussed in the context of stabilization of unusual square planar geometries for Al complexes, and in the context of the chemical reactivity that can be accessed via ligand-based electron and proton transfer reactions.
