Abstract

A dinuclear Fe(II) compound has been prepared through the reaction of 2,5-dichloride-4-phenylimino-1,2,4-triazole (L) with Fe(BF4)2·6H2O, with the formula [Fe2(L)5(SCN)4](H2O) (1). X-ray, magnetic, and 57Fe Mössbauer characterizations showed that compound 1 exhibited a spin crossover (SCO) behavior with T1/2 = 150 K. The study shows that introducing chloride groups on the ligand exerts a positive effect on increasing T1/2 and making SCO more complete. A LIESST effect was also observed for 1 through a light irradiation experiment.
