Summary
Complexes of Cu(II) and Zn(II) with 5-amino-2-thiol-1,3,4-thiadiazole (HATT - C<Subscript>2</Subscript>H<Subscript>3</Subscript>N<Subscript>3</Subscript>S<Subscript>2</Subscript>) can be obtained by the reaction of HATT with copper alloy corrosion products, which makes these complexes useful in the industrial field and in the conservation of bronze cultural heritage. This paper describes the study of the thermal decomposition of these complexes. TG/DTG, DTA, vibrational spectroscopy, X-ray diffraction and elemental analysis have been performed. Gaseous products (CO<Subscript>2</Subscript>, SO<Subscript>2</Subscript>, NO<Subscript>2</Subscript> and H<Subscript>2</Subscript>O) were evolved during the thermal decompositions. The final residues were CuO and ZnO.
