Abstract

A two-dimensional grid-like coordination polymer, [Fe(NCBH₃)₂(Py₂ttz)₂]·4CHCl₃ (1·4CHCl₃, Py₂ttz = 2,5-di(pyridin-4-yl)thiazolo[5,4-d]thiazole), showed one-step complete spin crossover with unexpectedly large hysteresis loop of 64 K wide and temperature-induced excited spin-state trapping effect below 91 K.
