Synthesis and characterization of Cu (II) complexes of salicylate ligands
Abstract
This work evaluates the synthesis and characterization of Cu (II) complexes of salicylate ligands using green method. The complexes were synthesized by direct mixing of the metal salt (CuCO3) dissolved in water and a corresponding ligand dissolved also in water. The complex was obtained in excellent yields (80%) by moderate heating in distilled water. The complexes were characterized by Ultra-Violet Spectrophotometer (UV-Vis), solubility, melting point and X-ray diffraction. Metal complex with formula of Cu (II)-L2 where L = acetylsalicylic acid and salicylic acid were obtained. The ligands gave crystalline complexes as it bonds to the central metal (copper).
