Cover Story: Aromaticity is one of the most important concepts in organic chemistry, and the proposed adaptive aromaticity (aromaticity in both the S0 and T1 states) breaks the limitation of traditional rules. In recent years, although adaptive aromatic compounds have been expanded, adaptive aromatics containing metal-centered radicals have not been reported. Here, we carry out density functional theory calculations to explore the aromaticity of the corresponding radicals based on osmapentalyne and osmapentalenes. Our findings reveal that the corresponding radicals of adaptive aromatic osmapentalene exhibit aromaticity regardless of the radicals formed by oxidation or reduction, supported by a series of aromaticity indices. Furthermore, the spin density localization on the metal center is the key factor for the radicals to achieve aromaticity. View this paper
