The solid-state behaviour of four alkali metal TCNQ complexes: (15-crown-5)LiTCNQ (1), (15-crown-5)NaTCNQ (2), (15-crown-5)Li(TCNQ)2.H2O (3.H2O) and (15-crown-5)Na(TCNQ)2.H2O (4.H2O) has been explored by single crystal X-ray diffraction, Infrared (IR), Raman and Electron Paramagnetic Resonance (EPR) measurements. The presence of a small cation and ionophore leads to subtle changes in behaviour compared with their larger alkali metal analogues and in the hydrated salts water bridges form links between the crown-encapsulated cations and neighbouring TCNQ stacks.
