Název v původním jazyce

Structure and Spectroelectrochemical Response of Arene-Ruthenium and Arene-Osmium Complexes with Potentially Hemilabile Noninnocent Ligands

Popis výsledku v původním jazyce

Nine of the compounds [M(L2-)(p-cymene)] (M = Ru, Os, L2- = 4,6-di-tert-butyl-N-aryl-o-amidophenolate) were prepared and structurally characterized (Ru complexes) as coordinatively unsaturated, formally 16 valence electron species. On L2--ligand based oxidation to EPR-active itninosemiquinone radical complexes, the compounds seek to bind a donor atom (if available) from the N-aryl substituent, as structurally certified for thioether and selenoether functions, or from the donor solvent. Simulated cyclicvoltammograms and spectroelectrochemistry at ambient and low temperatures in combination with DFT results confirm a square scheme behavior (ECEC mechanism) involving the L-n ligand ligand. as the main electron transfer site and the metal with fractional(delta) oxidation as the center for redox-activated coordination. Attempts to crystallize [Ru(Cym)(Q(SMe))](PF6) produced single crystals of [Ru-III(Q(SMe)(center dot-))(2)](PF6) after apparent dissociation of the arene ligand.
