A new poly[di(2,5‐dimercapto‐1,3,4‐thiadiazole)‐Pd(II)] complex (PDMT‐Pd) was synthesized by the reaction of 2,5‐dimercapto‐1,3,4‐thiadiazole (2 mmol) with palladium (II) chloride (1 mmol) in absolute ethanol under reflux for 24 hours. The products were characterized by elemental analyses, electronic spectra, FTIR spectroscopy, magnetic susceptibility, thermal analyses (TGA and DTA) and X‐Ray diffraction. The DC electrical conductivity variation with temperature of the polymer‐Pd (II) complex in the range 300–500 K was studied after annealing for 24 h at 100°C and after doping with 5% I2, for comparison.
