The C-O stretch as an unprecedently large spectral marker for the electron transfer between copper(II) and a phenolate anion

Abstract

An unprecedented red shift of more than 200 cm(-1) in the vibrational frequency of the C-O bond in the [Cu(PhO) L-n](+) complex (PhO = phenoxy), dependent on the number n of additional ligands L, is reported.
