Structural phase transition in a multi-induced mononuclear FeII spin-crossover complex†
Abstract
Herein, we report the investigation of a mononuclear spin-crossover complex [FeIIL2][ClO4]2 (L = 2,6-bis{4,4-dimethyl-4,5-dihydrooxazol-2-yl}pyridine). This compound undergoes a structural phase transition around 173 K, accompanying with an abrupt spin-transition process. Interestingly, it exhibits a multi-induced spin-crossover behavior mediated by heat, light, pressure and solvent.
