AbstractThe electrical conductivities of the compounds (CH3NH3)2CuCl4, (C2H5NH3)2CuCl4 and (CH2)2(NH3)2CuCl4 were measured in the temperature range which includes their structural phase transition. The values of the activation energies as calculated from the Arrhenius equation are reported. Confirmation of the phase transition temperatures is carried out using differential thermal analysis in the same temperature range as the conductivity measurements. © 1983.
