Optimized procedures to [7]heliphene are described that allowed the synthesis of ((6)-[7]heliphene)tricarbonylchromium and a preliminary exploration of its chemical behavior. DFT calculations provide structural and energetic information on this complex and its haptomeric isomers. Attempts to prepare the corresponding ([7]heliphene)chromium sandwich failed so far, but DFT evidence is presented to indicate that the target should be accessible.
