Molecular Approach to Alkali-Metal Encapsulation by a Prussian Blue Analogue Fe^II/Co^III Cube in Aqueous Solution: A Kineticomechanistic Exchange Study.

ABSTRACT: The preparation of a series of alkali-metal inclusion complexes of the molecular cube [{Co^III(Me₃-tacn)}₄{Fe^II(CN)₆}₄]^4- (Me₃-tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane), a mixed-valent Prussian Blue analogue bearing bridging cyanido ligands, has been achieved by following a redox-triggered self-assembly process. The molecular cubes are extremely robust and soluble in aqueous media ranging from 5 M [H⁺] to 2 M [OH^-]. All the complexes have been characterized by the standard mass spectometry, UV-vis, inductively coupled plasma, multinuclear NMR spectroscopy, and electrochemistry. Furthermore, X-ray diffraction analysis of the sodium and lithium salts has also been achieved, and
