The cover depicts the 3D surface of a natural bond orbital exhibiting a 3 centre—4 electron crossover π ^ long‐bond between carbon atoms spatially separated by a nitrogen atom in a linear isomer of C 6 N radical. On page 1568 (DOI: 10.1002/jcc.23657 ) Gurpreet Kaur and Vikas report this unprecedented chemical‐bond “type” is supposed to stabilize a high‐lying linear isomer of the C 6 N radical, centrosymmetric with respect to the nitrogen atom, which otherwise can readily dissociates to C 3 and C 3 N fragments. Though such long‐bonding hasnot yet received much appreciation, its σ ^ analogue has been successfully used to visualize “molecular‐metallic” phenomena.
