From disorder to order and back: Contrary to all earlier studies on [Fe(2‐pic) 3 ]Cl 2 ⋅EtOH (pic=picolylamine), an ordered phase (IP) with two crystallographically different iron sites was found between disordered high‐spin (HS) and low‐spin (LS) phases. The picture shows the average FeN distances of all three phases.
