Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Quintuple bonds</bold> between chromium atoms are the first choice for looking at how short a metal–metal bond can be. In their Full Paper on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 9825 ff., </ext-link> L. Gagliardi, R. Kempe et al. describe a rational concept of shortening quintuple bonds based on ligand design. A Cr–Cr distance of 1.7056(12) Å is the value finally reached. Most importantly, the potential limitations of the shortening concept and the formation of other coordination isomers or over‐reduction are described.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg2712011q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
