Abstract

<jats:title>Abstract</jats:title> <jats:p>Spectroelectrochemistry of [5]radialenes with five 1,3-dithiol-2-ylidenes (DTs) (1) was carried out. The UV–vis–NIR spectra of 12+ suggest delocalization of two positive charges over three DT units. X-ray structure analysis of an oxygen adduct (2)2+(AsF6−)2(PhCl)1.5 reveals that 22+ has a cyclopentadienide structure in the central five-membered ring.</jats:p>
