The dependence of the electrical conductivity of aniline and its derivatives in situ intercalated within the cavities of the three dimensional polymeric host [(Me3Sn)3Fe(CN)6]infinity, on temperature has been investigated. The conductivity values at 303 K, the activation energies and the energy gaps have been calculated. These novel polymeric intercalated complexes behave as good semiconductors. The conductivity depends on the structure of the aniline derivative and the conditions of the reaction.
