Description:
AbstractA single‐crystal radical cation salt was obtained by anodic oxidation of trans‐1,2‐bis‐(2‐naphthyl)ethene (1,2‐DNE) with SbF−6 as the counter‐ion. The crystal structure of (1,2‐DNE)SbF6 was solved and found to be similar to the radical cation salts of unsubstituted naphthalene. The crystal structure is disordered, i.e. two orientations of the 1,2‐DNE molecules are statistically occupied. The molecular overlap, resulting from these two orientations, models the structure of the salt of poly(2,6‐naphthylenevinylene). In contrast to most other radical cation salts which are one‐dimensional conductors, a conduction mechanism of higher dimensionality is predicted on the basis of the crystal structure of (1,2‐DNE)SbF6. The identical type of disorder is also present in the crystal structure of trans‐1,2‐bis(1‐naphthyl)ethene.
