摘要: Abstract Two new naphthoquinone derivatives, 5-dodecanoylamine-8-hydroxy-l,4-naphthoquinone (1) and 5-dodecanoylamine-8-acetoxy-l,4-naphthoquinone (2), have been prepared characterized. Their chelating ability with Ni(II) Co(II) studied. Compound coordinates to the divalent metal ions as a monoanionic bidentate ligand. The complexes were found contain two ligands molecules of coordinated water. structure bonding chelates are discussed based on spectroscopic data.
