Anionic borate‐based bi‐mesoionic carbenes based on 1,2,3‐triazol‐4‐ylidenes show unique C−N isomerization reactions. In their Research Article on page 499, Biprajit Sarkar and co‐workers report on the isomerized ligands in Co II complexes. The picture shows these complexes, which, despite having a similar first coordination sphere, differ in geometry, spin state, and reactivity. All of these differences are caused by the control of the second coordination sphere, in which agostic interactions influence the cobalt center.
