摘要：

Thermal decomposition of the title compound, Zn(tu)(2)Cl-2 (tu=thiourea), was studied up to 1200degreesC in dynamic inert (N-2) and oxidative (air) atmospheres using simultaneous TG/DTA techniques. In addition, XRD and IR were employed ex situ to resolve the reaction mechanism and products. Cubic ZnS (sphalerite) is formed below 300degreesC in both atmospheres and is observed until 760degreesC, whereafter it transforms in nitrogen to the hexagonal ZnS (wurtzite). EGA by FTIR revealed the complexity of the decomposition reactions involving also the evolution of H2NCN, which reacts to form hexagonal ZnCN2 as shown by an XRD analysis.
