Synthesis, structural characterization and biological properties of ortho-quinone derivatives and their metal conjugates
"The synthesis and characterization of the Phenanthrenequinone Semicarbazone, 4-phenylsemicarbazone and Benzoic Hydrazone with 1,2-naphthoquinone-monoxime are reported. The X-ray crystal structure of the Phenanthrenequinone Semicarbazone (PQSC), 4-phenylsemicarbazone (PQPSC) and Benzoic Hydrazone (PQBH) confirms the presence of the E tautomeric arrangement in these compounds. The free 1,2-naphthoquinone-monoximes exist in the quinonemonoxime form. The X-ray crystal structure of the complexes, viz. [Ni(PQSC)₂], [Zn(PQSC)₂], reveals that the SC ligands behave as a tridentate monoanionic ligand coordinating through quinone oxygen, enolate oxygen, and azomethine nitrogen forming a distorted octahedron with the metal ion at the center. The nickel, cobalt and zinc complexes show 1:2 stoichiometry while copper complex shows 1:1 metal to ligand ratio in all the synthesized metal complexes"--Abstract, leaf iii.
