New binuclear mercury complex: Synthesis, supramolecular structure, physico-chemical characterizations and antibacterial activity

Abstract Newly synthetized Mercury (II) coordination complex with the following general formula [HgL(Cl)2]2, (L = C12H12N2O2S: 4,4’-diaminodiphenyl sulfone), was obtained by slow evaporation technique at room temperature. Single crystal X-ray diffraction shows that it crystallizes in the monoclinic system with P21/c space group. The studied compound is mainly a chloro bridged binuclear complex with tetrahedral coordination environment around each metal center. The stability of the crystal structure is ensured by mans of hydrogen bonds. In order to examine the interactions between the different present species, Hirshfeld surface analysis (HS) was also carried out. Optical studies, conducted after the thermal examination of the material, reveal that the title compound is apt to be considered as a powerful semiconductor. Lastly, the antibacterial activity was evaluated against Gram positive and Gram negative using the agar diffusion method.
