Prussian blue analogues (PBAs) form a versatile family of inorganic polymers that may exhibit promising electronic and magnetic properties. Owing to the partially disordered structure of these systems, a comprehensive characterization of PBAs is often tricky and requires the use of numerous complementary techniques. We present herein an original use of infrared (IR) spectroscopy in the characterization of PBAs. Based on a detailed assignment of both the far- and mid-IR spectra of PBAs, including the description of the metal-ligand bonds and the water molecules in PBAs, we demonstrate that IR spectroscopy allows investigating the electronic and structural properties of PBAs.
