Abstract
The electrical behaviour of hydroxyquinoline sulfonic acid and its com plexes with Mn(II), Fe(II), Co(II), Ni(II) or Cu(II) as well as its sa lts with Li(I), Na(I) or K(I) were studied over the temperature range 294-420 K. All compounds behave like semiconductors. The stability con stants were calculated at different temperatures in order to determine the thermodynamic parameters Delta H, Delta G and Delta S for the com plexes studied. The composition and structure of the complexes were fo llowed using conductometric titration and IR measurements.
