Spin crossover complexes show great potential as molecular switches or data storage devices. For a good performance as such, the switching between the high spin (HS) and the low spin (LS) state should be abrupt and show a stable hysteresis in an accessible temperature region. We report the synthesis and characterization of a spin crossover coordination polymer exhibiting such attributes. By differential scanning calorimetry and magnetic measurements, Mössbauer spectroscopy, and X-ray powder diffraction, we revealed a wide and stable hysteresis of the spin transition between T1/2, up = 371 K and T1/2, down = 323 K, which can additionally be tracked using photoluminescence spectroscopy due to a change in emission color.
