Abstract

This article focuses on the development and characterization of a compact transmission heating cell designed for in situ temperature-dependent x-ray absorption spectroscopy (XAS) measurements, particularly targeting spin crossover (SCO) complexes. The cell achieves high temperature stability (fluctuations below 0.04 °C) and minimal overheating (<0.8 °C) up to 355 °C in air and 500 °C under vacuum, enabling reliable investigation of temperature-induced spin transitions. Its performance was validated through measurements of the iron(II) SCO complex [Fe(bzimpy)₂](ClO₄)₂ · 0.25H₂O using both a laboratory von Hámos XAS spectrometer and synchrotron radiation at the DELTA storage ring, demonstrating consistent spectral changes corresponding to the spin transition. The design allows for fast temperature ramps and is adaptable for other materials and experimental setups, making it suitable for broader applications in material science and catalysis research.
