Tóm tắt

The triplet benzene dianion is predicted to be aromatic based on Baird's rule. However, it has remained elusive due to the Jahn-Teller distortion. Herein, we report isolation of a benzene dianion with a triplet ground state in an inverse-sandwich europium benzene complex. Combined experimental and theoretical studies unveil that the strong antiferromagnetic coupling between the benzene dianion and 4f
