Photoswitchable Dynamic Magnetic Relaxation in a Well-Isolated {Fe2Co} Double-Zigzag Chain

Charge‐transfer‐induced spin transition occurs cooperatively and reversibly in the isolated FeIII2CoII chains of {[Fe(pzTp)(CN)3]2Co(4‐styrylpyridine)2}⋅2 H2O ⋅2 CH3OH (1). When 1 is irradiated with 532 nm light, it shows single‐chain magnetic behavior with no antiferromagnetic ordering after irradi...

Summary:Charge‐transfer‐induced spin transition occurs cooperatively and reversibly in the isolated FeIII2CoII chains of {[Fe(pzTp)(CN)3]2Co(4‐styrylpyridine)2}⋅2 H2O ⋅2 CH3OH (1). When 1 is irradiated with 532 nm light, it shows single‐chain magnetic behavior with no antiferromagnetic ordering after irradiation (see picture; C gray, N blue, B yellow; LS=low spin, HS=high spin).
