“…The Fe 2p 3/2 region appears particularly useful to obtain information on the valence and electronic configuration of the iron atom ( Figure 3). For K 4 [Fe(CN) 6 ]·3H 2 O, in this region the single peak of low spin Fe II species appears. This peak was found at 708.1 eV, accompanied of a weaker contribution at 709.0 eV from a high spin Fe 2+ species; with the corresponding satellite at higher energy value (712.1 eV).…”

“…The N 1s peak shows certain sensibility to the π-back donation effect that appears when the CN ligand is coordinated to inner metal to form the complex anion. Relative to its position in KCN, in the complexes a negative shift for the binding energy was observed, which is of -0.7 and -0.5 eV for K 4 6 ], respectively ( Figure 2). This is consistent with the above discussed difference in π-back bonding charge donation to the CN ligand in the ferrous and ferric complexes.…”

“…electron density removed from the inner metal through that mechanism, and accumulated on the N end, is higher for K 4 [Fe(CN) 6 ]·3H 2 O and this is sensed as a lower binding energy for N 1s peak for this last salt. The inverse effect explains the slightly smaller binding energy shift for N 1s in K 3 [Fe(CN) 6 ] relative to the ferrous anion.…”

“…The net effect is an overlapping for the electron clouds of the involved metals (M, T). This explains the attractive properties of this family of materials as prototype of molecular magnets, which have been widely studied in the last decades The presence of two redox centers linked through the CN bridge and for some compositions also of an exchangeable alkali metal (A), has stimulated their study as materials for new generation of batteries, in electrochemical sensors, environmental remediation,, and for health care . For certain combinations of metals, e.g.…”

This study reports an evaluation on the scope of X‐ray photoelectron spectroscopy (XPS) to obtain information for the coordination chemistry of transition metal (Tn) hexacyanometallates, TxAz[Mm(CN)6]y where nx +z = y(6 – m), A is an alkaline charge‐compensating cation, and Mm is a transition metal with a maximum of 6 electrons in its nd orbitals. XPS provides an elegant picture on the role of the CN π‐back bonding effect to determine the charge density on the N atom and, from this fact, on its coordination to transition metal ions to form coordination polymers. XPS appears to be able to discriminate between octahedral and tetrahedral coordination for the outer metal (T) to the N end of CN ligands, particularly when the XPS peak and the Auger lines are combined. A similar performance was observed when this spectroscopic technique is used to identify when the CN ligand is found with linear and bifurcated coordination mode to the metal linked at its N end. These last two structural features are relevant in the coordination of metal hexacyanometallates and determine their physical and functional properties. The results obtained from XPS data were correlated with the a priori information from IR spectra and the reported crystal structures for all the samples under study.

In recent years, Prussian blue analogue (PBA) materials have been widely explored and investigated in energy storage/conversion fields. Herein, the structure/property correlations of PBA materials as host frameworks for various charge‐carrier ions (e.g., Na+, K+, Zn2+, Mg2+, Ca2+, and Al3+) is reviewed, and the optimization strategies to achieve advanced performance of PBA electrodes are highlighted. Prospects for further applications of PBA materials in proton, ammonium‐ion, and multivalent‐ion batteries are summarized, with extra attention given to the selection of anode materials and electrolytes for practical implementation. This work provides a comprehensive understanding of PBA materials, and will serve as a guidance for future research and development of PBA electrodes.
