D.C. Conduction Phenomenon of some Rhodanine Azo Complexes

The electrical behaviour of 5-(4-R-phenylazo)-3-phenyl-2-thioxothiazolidin-4-one compounds and their complexes with Co²⁺, Cu²⁺, and UO₂⁺² was investigated in the temperature range 300—450 K. The conductivities were found to depend on the structure of the compounds and the metal ions. Both the structures of the azo and the complexation process play an effective role in the conductionprocess. The activation energy, ∆E, increases by decreasing the conductivity of the complexes.
