Radical–Radical Recognition: Switchable Magnetic Properties and Re-entrant Behavior

What is it about?

Pancake bonds between radical ligands can be reversibly made/broken to generate a switchable system with multiple magnetic and structural states.

Why is it important?

A generally application theoretical approach demonstrates that competition between a magnetic term intrinsic to the radical ligands and an elastic term representing the flexibility of the crystal lattice is sufficient to generate re-entrant phase behaviour.
