Two-step magnetic switching in a mononuclear iron(ii) complex around room temperature†
Abstract
A neutral mononuclear Fe(II) complex with spin crossover (SCO) properties, FeL2(SCN)2 (1) (L = 2-(2-(trifluoromethyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), was solvothermally synthesized. It displays a new example of two-step SCO with Tc1↓ = 250 K, Tc1↑ = 260 K and Tc2 = 295 K.
