Structural phase transition in a multi-induced mononuclear Fe-II spin-crossover complex

Herein, we report the investigation of a mononuclear spin-crossover complex [(FeL2)-L-II][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.NSFC [21071008, 21321001, 21371043, 21302035]; National Basic Research Program of China [2010CB934601, 2013CB933401]; Fundamental Research Funds for the Central UniversitiesSCI(E)EIPubMedARTICLEyyzhu@hfut.edu.cn; liutao@dlut.edu.cn; gaosong@pku.edu.cn4820906-209124
