Abstract

A pure mixed-anion Fe(NH₂trz)₃(BF₄)(SiF₆)_0.5 spin crossover complex is obtained implementing a solid-liquid post synthetic modification approach from the Fe(NH₂trz)₃(BF₄)₂ parent complex. This method allows obtaining highly crystalline powder samples incorporating homogeneous micrometric (1 μm long) rod-shaped particles. This compound presents an abrupt spin crossover behaviour with a narrow (10 K) hysteresis loop centred just above room temperature (320 K) which makes it very interesting for future integration into devices for various applications.
