On page 7570, A. P. O'Mullane, V. Bansal, and colleagues show how the spontaneous reaction of Ag+ ions with a pre‐fabricated CuTCNQ metal‐organic charge transfer complex results in different CuTCNQ/AgTCNQ hybrids in different solvents. The reaction in acetonitrile forms a pure CuTCNQ/AgTCNQ hybrid through a process of corrosion‐recrystallization. Conversely, in water, CuTCNQ undergoes a galvanic replacement reaction with Ag+ ions that results in additional decoration of newly‐formed CuTCNQ/AgTCNQ hybrids with Ag nanoparticles and Cu(OH) 2 crystals.
