Disentangling chemical pressure and superexchange effects in lanthanide-organic valence tautomerism

Chem. Sci., 2025, Accepted Manuscript DOI: 10.1039/D5SC01246E, Edge Article Anton Viborg, Maja A Dunstan, Nathan J. Yutronkie, Amit Chanda, Felix Trier, Nini Pryds, Fabrice Wilhelm, Andrei Rogalev, Dawid Pinkowicz, Kasper Steen Pedersen Valence tautomerism in molecule-based f-block materials remains virtually elusive. As a result, the effects driving and controlling the valence conversion phenomenon are poorly understood. Herein, we unravel these fundamental factors...
