Synthesis and Antimicrobial Study of Complexes of New Schiff?s Bases derived from 3-Acetyl-4-Hydroxy-2H-Chromen-2-One & Semicarbazide with Cu (II) And Ni (II) Metals

V. V. Kodgire [3]

Abstract: Cu (II) and Ni (II) Metal complexes of 3-acetyl-4-hyrdoxy-2H chromen-2-one and semicarbazide are synthesized by various methods. In the present work they are synthesized by reacting methanolic solution of ligand and metal chloride followed by precipitating the complex by addition of alcoholic ammonia. The ligand to metal ratio for copper and nickel complexes is 2: 1 suggesting monomeric nature All the Cu (II) and nickel (II) complexes synthesized are coloured and stable to air and moisture. Most of them decompose at high temperature. They are insoluble in water, common polar and non-polar solvents. The complexes are sparingly soluble in methanol, ethanol, chloroform, dimethylformamide (DMF) and dimethyl sulphoxide (DMSO). The complexes were synthesized and characterized by elemental analysis, IR, electronic spectra, molar conductance, TGA and powder XRD. The antimicrobial activities of the ligand and their metal complexes were screened by Agar cup method.
