Controlling A _x Mn[Fe(CN)₆] charge transfer pathways through tilt-engineering for enhanced metal-to-metal interactions.

ABSTRACT: The induction of structural distortion in a controlled manner through tilt engineering has emerged as a potent method to finely tune the physical characteristics of Prussian blue analogues. Notably, this distortion can be chemically induced by filling their pores with cations that can interact with the cyanide ligands. With this objective in mind, we optimized the synthetic protocol to produce the stimuli-responsive Prussian blue analogue A _x Mn[Fe(CN)₆] with A = K⁺, Rb⁺, and Cs⁺, to tune its stimuli-responsive behavior by exchanging the cation inside pores. Our crystallographic analyses reveal that the smaller the cation, the more pronounced the structural distortion, with a notable 20-degree Fe-CN tilting when filling the cavi
