Abstract

Semiquinone radical anion (Q˙−) forms a stable π-dimer with neutral p-benzoquinone (Q), bridged by two or three scandium ions (Sc3+) to afford Q˙−–nSc3+–Q (n = 2,3), which is in disproportionation equilibrium with Q and hydroquinone (QH2). The number of binding scandium ions changes depending on temperature, causing a remarkable color change associated with the change in the ESR spectra.
