Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Long CC bonds</bold>: Analysis of the 1064 nm Raman vibrational spectrum of K₂[TCNE]₂ possessing isolated π‐[TCNE]₂²⁻ (TCNE=tetracyanoethylene) dimers shows several low‐energy symmetric intradimer breathing modes at 198, 173, 155, 131, 107, and 85 cm⁻¹. These data confirm the presence of a long two‐electron/four‐center CC bond (see picture).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg21kr28qn" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
