A [7]helicene bis‐ruthenium complex, with one ruthenium atom bound to the cyclopentadienyl (Cp) ring and the other coordinated to the arene ring at the edge of the helicene, was synthesized. This complex showed phosphorescence both in butyronitrile ( Φ =31 %, 77 K) and in the solid state ( Φ =18 %, 77 K). The two non‐equivalent ruthenium metal atoms, attached to the helicene ligand, interact with each other upon photoabsorption and emission.
