The thermal behavior and thermal properties of the metal cluster 4 (n-Bu) 4N 犦 3 犤 WS4Ag3X3Br 犦 (X = Cl, Br, I) in a dynamic nitrogen atmosphere were investigated by TG-DTG- In the process of thermal decomposition, the elemental intermediates in each step of the reaction were followed up and the corresponding decomposition components were judged; and their physical structures were discussed. The kinetic analysis of each reaction was carried out. The complexity of reaction was discussed by the dependence of activation energy and reaction process.
