Preparation of Some (Transition Metal-Flavylium Salt- Substitutes Chalcon) Com

Abstract

Three ligands were prepared and spectroscopic method and elemental analysis verified their structures. Two of the ligands L1 and L2 are flavylium salts and the third L3 is a chalcone. Reaction between transition metal salts and the ligands have synthesized two groups of new metal complexes. One group contains L1, L3 and the metal. The other group contains L2, L3 and the metal. These complexes have been identified by available spectroscopic tools (UV-visible ,IR and 1HNMR), the C.H.N results confirmed the proposed structures. The experimental data disclosed that the complexes were coordinated by 6- the coordinate with mono-and bidentate ligands forming octahedral structure, in which L3 acts as monodentate and L1, L2 as bidentate ligands. The metal linked with L1 and L2 through the oxygen in ortho position in ring B, were as the linkage of the metal with L3 takes place through the oxygen of the carbonyl group.
