ABSTRACT The complexes of Pd (II), VO Cu and Ni (II) with Schiff base (ABDS) derived from 2‐aminobenzothiazole 4‐(diethylamino)salicylaldehyde have been prepared. Various spectroscopic methodologies for analysis, which might include 1 H, 13 C NMR, infrared spectra (IR), ultraviolet–visible (UV–vis), magnetic values, applied to elucidate the construction these chemicals. For each complex, most suitable form has proposed as a result. chemical compound behaves bi‐dentate via NO donors into material ions within octahedral shape about 2+ , geometry square pyramidal planner around ion. substances were tested against different bacterial fungal strains. They demonstrated effective inhibition harmful bacteria under study cytotoxic activity (IC 50 ) (HCT‐116 cell line), (HepG‐2), (MCF‐7). metal chelates shown possess more antimicrobial than free chelate. ABDS ligand had only moderate antioxidant activity, but combined forms V (IV), exhibit ligand. These findings also corroborated hypothesis that combinations produced effects DPPH radicals comparable those regular vitamin C.
