  "abstract": "The preparation, crystal structure and electrochemical properties of a novel tetrathiafulvalene (TTF) derivative 1 substituted by two selenomethyl moieties are reported, with the aim to highlight the occurrence of chalcogen bonding interactions through activation of one of the two σ-holes on each Se atom, upon TTF oxidation into cation radical. Oxidation with iodine led to two different ionic phases incorporating 1+˙, with short and directional Se⋯I ChB interactions. In both salts, the 1+˙ radical cations are associated into diamagnetic dimers through a strong face-to-face, eclipsed, SOMO–SOMO interaction. Two different TCNQ salts were isolated, (i) a neutral charge-transfer complex with the weakly oxidizing TCNQMe2 and (ii) an ionic charge transfer salt with the stronger oxidant TCNQF2. In both co-crystals a Se⋯NC ChB bond is observed, in the prolongation of the CTTF–Se bond, with a notably stronger ChB within the ionic salt with TCNQF2, demonstrating the efficient charge activation of the ChB in these two closely related compounds, with alternated stacks of TTF and TCNQ derivatives.",
