Preparation and Characterization of Schiff Base Ligand Complexes Derived from Dimedone with Urea

Abstract

Eight complexes of this group were created in this work by reacting the novel ligand that was produced from the reaction of dimedon with urea with the chlorides of trivalent elements (Iron and Chromium) and divalent transition elements (Manganese, Cobalt, Nickel, Copper, Platinum, and Cadmium). These complexes had unique hues, melting temperatures, and solubility's based on the diagnostic data, it was discovered that the ligand1,5,5-carbamoylimino-3,3-dimethylcyclohexylidene urea (L1) It attaches to the metal ion by two amine groups and functions as a Bi-dentate ligand . IR, UV-visible, Molar electrical conductivity, and Magnetic susceptibility Spectra all suggested Paramagnetic characteristics for the complexes, with the exception of Zinc and Cadmium are Dimagnetic, and Molar conductivity revealed that all the complexes are non-Electrolytic, with the exception of Iron and Chromium. These data suggested that the complexes were Octahedral in shape. Elemental analysis was used to identify the molecular formula of the complexes that made up the group, and the elemental percentages agreed with the suggested molecular formula. The outcomes demonstrated that the complexes' biological activity against pathogenic bacteria exhibited a range of efficacy. When ethanol was used as a test substance for antioxidant efficacy, the results varied in terms of efficacy and were compared to gallic acid using DPPH as a free radical, yielding differing IC₅₀ values.
