چکیده
Schiff bases are very popular ligands for inorganic chemists because of their easy synthesis, structural variety and high coordinating ability for different metal ions [1]. these compounds and their metal complexes form important class of materials in medicinal chemistry with various biological activities including urease inhibitory, antitumour, antifungal, antibacterial, antiproliferative, anti-inflammatory, antiviral and insulin-enhancing activities [2].In this study, a new series of cadmium halide/pseudohalide complexes with a novel Schiff base ligand containing imidazolidine ring has been successfully synthesized. Schiff base ligand and its complexes were characterized by FT-IR, 1H, 13C NMR, UV–Vis spectra, thermal analyses and molar conductance measurements. based on spectral data, the general formula of CdLX2 (X = Cl-, Br-, I- and SCN-, N3-, NO3-) was proposed for the cadmium complexes. CdO nanoparticles were prepared by direct calcination process of cadmium bromide complex at 600°C under air atmosphere. the cadmium compounds in nano-structure size were also prepared by sonochemical method. the nano-structure compounds were characterized by Xray diffraction (XRD) and scanning electron microscopy (SEM). furthermore, antibacterial activities of compounds have been screened against various bacteria and fungi by disk diffusion method. finally DNA cleavage potential of the compounds was investigated by agarose gel method.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
