The d.c. conductivity, a.c. conductivity and thermoelectric power of the compounds H3N+(CH2)+ NH3FeCl4, where n=2, 3, 7 and 10, have been studied over a temperature range of 150-500 K. The conductivity results confirm the presence of more than one structural phase transition for each compound investigated. The thermoelectric power measurements showed that electrons are the main charge carriers in all crystal phases. The conductivity results were explained on the basis of an electron hopping mechanism over the whole temperature range. © 1988 Chapman and Hall Ltd.
