Hydrothermal synthesis is a versatile tool for the preparation of materials, hard‐to‐access compounds, and high‐quality single crystals. However, as is described by D. B. Leznoff, R. H. Hill et al. on page 7156 ff., when high‐dimensional Prussian Blue analogue cyanometallate coordination polymers are prepared by this method, it is also possible to inadvertently prepare magnetic nanoparticles that usurp the observed magnetic properties. As depicted by the flow diagram, a much closer look is required to properly identify the culprits, which are present in such minute amounts as to be undetectable by conventional analysis methods, thereby misleading one to believe the prepared material is pure and pristine.
