Wang et al. in their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 2857 ff.</ext-link> The ground‐state structures of three bis(triphenylamine) dications, isolated by using weakly coordinating anions, were tunable through the donor substituents at the <italic>para</italic> positions of the triphenylamines. This gave rise to closed‐shell singlets and a new and stable diradicaloid structure motif with an excited triplet state in the solid state.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4srjpkvm" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
