The effects of mercury complexes on human body and cells vary depending on the extent of exposure and their pharmacological form. Objectives: To characterize mercury complex and then investigate the effects on cellular interaction via cell death. Methods: The synthesis of the mercury complex was carried out, and its characterization was done by FTIR, elemental percentage and powder X-ray diffraction (PXRD). The complex was analyzed through atomic force microscopy (AFM) and by microscopy imaging its surface morphology and cellular interaction were also studied. Results: The presence of the mercury-complex results in cell death in concentration and time dependent manner. Conclusions: The synthesized mercury-complex has the ability to harm cells.
