The thermal decomposition of the complex AgCl.2CS(NH2)2 was studied with the aid of IR spectroscopy, DTA, and TG anal. A mechanism is proposed, which includes the transformation of the thiourea ligand to NH4NCS at 210-230?followed by further decomposition The apparent activation energy and the preexponential constant were calculated
