Abstract
The radical cations and the radical of 1,2‐bis(phenalen‐1‐ylidene)ethane (1), 1,2‐bis(phenalen‐1‐ylidene)ethene (2) and pentaleno[1,2,3‐cd: 4,5,6‐c′ d′]diphenalene (3) have been characterized by ESR and ENDOR spectroscopy. The ease of formation of these radical ions and their π‐spin distributions are interpreted in terms of a simple model correlates the frontier orbitals of 1, 2 and 3 with the nonbonding MO's of two phenalenyl π‐systems.
