σ‐Aromaticity has traditionally been observed in saturated rings (illustrated by the cage). Now, a combined theoretical and experimental study on osmapentaloselenirenes demonstrates the first example of σ‐aromaticity dominating in an unsaturated Se‐containing ring, thus extending σ‐aromaticity to an unsaturated system (illustrated by the area outside the cage).
