“…In fact, there are lone pair electrons on nitrogen and sulfur atoms of each TAA, which provides the possibility that TAA can combine with the Cu 2+ ions to form a Cu 2+ −TAA complex as in the case of the transition metal ions M 2+ (M = Cu, Cd, Zn, Ni, etc. ). , It can be inferred that the complex possibly has a composition of [Cu−(TAA) 2 ]Cl 2 . The thermal stability of the complex was examined by TGA.…”
