Abstract:	The influence of complexation with some divalent transition metal cations on the electrical behavior of 4-amino-3-hydroxy-1-naphthalenesulfonic naphthalenesulfonic acid has been studied over temperature range 294-450 K. The complexes behaved as typical organic semiconductors. The stability constants of different complexes were determined. Their compositions were characterised using conductometric titration and infrared techniques.
