Abstract
Electrical conductivity of 5-(substituted arylazo)thiobarbituric acid complexes were measured in the temperature range 298 - 573 K. The resu lts were correlated to the geometrical structure. The electrical condu ctivity data illustrate faint semiconducting behaviour for these syste ms. In general, electron donor substituents gave higher DELTAE values compared to the electron attracting groups. Empirical equations have b een constructed to correlate the variation of the activation energy, D ELTAE (eV), with log sigma(o).
