The decachlorocadmate (II) cluster templated with homopiperazinium cation (C5H14N2)2[Cd3Cl10]·4H2O has been grown using the slow evaporation method and characterized by X-ray diffraction, FTIR, Raman, 1H and 13C-NMR spectroscopies. Thermal investigations have also been made for the title compound. The X-ray structural analysis has elucidated the different inter-contacts in the crystal structure between the [Cd3Cl10]4− clusters, the water molecules and homopiperazinium entities stabilizing the 3D-supramolecular structure. These thermal investigations have also revealed a double dehydration phenomenon at around 96 and 125 °C. The TG curve shows that the compound is stable up to the decomposition temperature of around 317 °C. The title compound has been tested for its in vitro antioxidant and antibacterial activities. The 1,1-diphenyl-2-picrylhydrazil (DPPH) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) test has shown that the compound synthesized is characterized by a significant antioxidant activity when compared to ascorbic acid and that it is active against all the tested bacteria. Nevertheless, bacteria sensitivity depends on the bacterial membrane structure. Indeed gram-negative bacteria are more sensitive to the compound tested than the gram-positive ones.
