Abstract
Circular dichroism (CD) spectroelectrochemistry is used to determine the extent of singly occupied molecular orbital delocalization in mixed-valence multinuclear complexes, specifically the mixed-valence Ru IIRu III states of the four diastereoisomers of [(Ru(bpy) 2) 2(bpt)] 3+ [1; bpy = 2,2′-bipyridyl and bpt = 3,5-bis(pyrid-2′-yl)-1,2,4-triazolato anion]. The complex was found to be stable to thermal racemization in the three oxidation states, but photoracemization in the Ru IIRu II state was observed. © 2011 American Chemical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
