[Fe(bpp)2][Pt(ox)2]·H2O (with bpp = 2,6-bis(pyrazol-3-yl)-pyridine and ox = oxalate) was prepared, and its spin crossover behavior was characterized. The two-step spin transition behavior changes over several cycles. The original behavior is restored when the sample is allowed to relax for a week. Furthermore, the ST exhibits a strong dependence on the heating and cooling rate...
