摘要:A novel three-dimensional (3D) Fe(II) metal-organic framework (MOF), [Fe _2(pptp) _42H _2O] _n (1), constructed from the rigid 2-(3-(4-(pyridin-4-yl)phenyl)-1H-1,2,4-triazol-5-yl)pyridine (Hpptp) ligand was synthesized and structurally characterized. Complex 1 exhibits a two-dimensional (2D) → 3D polycatenated framework based on inclined interlocked 2D 4 ~4-sql grids. Variable-temperature magnetic susceptibility measurements reveal that 1 is a rare example exhibiting a thermal-driven dehydration and consequently accompanied by a dramatic change of spin crossover (SCO) behaviors. Its spin transition temperature is as high as 390 K with ~20% high-spin character. Moreover, the framework of 1 shows unusual thermal stability to nearly 500 °C.
