In this research, a new Ag(I) complex, namely, [Ag(5-chloro-1H-benzimidazole)2(NO3)], has been synthesized using the benzimidazole-based ligand 5-chloro-1H-benzimidazole (5ClBZ). Ag(I) complexes were characterized by elemental analysis, UV-Vis, FT-IR, and 1H NMR spectroscopy, and DFT analysis was used. The free ligand and its Ag(I) complexes were tried for their biochemical properties, including antioxidant and antidiabetic properties. To study the molecular structures of the title compounds, in silico ADME/Tox research was performed on the newly made complex and free ligand. The empirical guidelines relating to ADME were utilized to conduct molecular docking simulations and in-depth drug-likeness profiling. This was carried out to validate the conclusions and identify exact binding interactions. Based on the study's findings, it has been determined that these new compounds have significant potential as powerful therapeutic agents for controlling antioxidant and antidiabetic activities.,In this research, a new Ag(I) complex, namely, [Ag(5-Chlorobenzimidazole)2NO3], has been synthesized and characterized by elemental analysis, IR, UV-Vis, and 1H NMR spectroscopy. The electronic behavior of the compounds were investigated with DFT method. Also, antioxidant and antidiabetic properties of the ligand and its Ag(I) complex were investigated. image
