Abstract
A mixed-valence Fe(II)Fe(III) molecular system, Fe(pzTp)(CN)32Fe(bik)22·Fe(pzTp)(CN)32·4MeOH (1·4MeOH) (bik = bis-(1-methylimidazolyl)-2-methanone, pzTp = tetrakis(pyrazolyl)borate), exhibits single-crystal-to-single-crystal (SC-SC) transformation while increasing the temperature and is converted into {Fe(pzTp)(CN)32Fe(bik)22}·Fe(pzTp)(CN)32 (1). Both complexes exhibit thermo-induced spin-state switching behavior along with reversible SC-SC transformation, where the low-temperature FeIIILSFeIILS2 phase transforms into a high-temperature FeIIILSFeIIHS2 phase. 1·4MeOH exhibits an abrupt spin-state switching with T1/2 at 355 K, whereas 1 undergoes a gradual and reversible spin-state switching with a lower T1/2 at 338 K. Astonishingly, 1 exhibits ON/OFF photo-induced spin-state switching with TLIESST = 67 K, whereas 1·4MeOH does not show such an effect. © 2023 American Chemical Society.
