A Schiff base ligand, H2L, was prepared by the condensation of o‐acetoacetylphenol with ethylamine in the molar ratio 1:1. The Schiff base acts either as monobasic or dibasic ligand and contains O,O,N coordination sites. It reacts with the cations

Two novel asymmetrical Schiff-base ligands, H2L1 and H2L2, were prepared by reacting two half-unit Schiff-base compounds with 2-methyl-7-formyl-8-hydroxyquinoline. The two half-unit Schiff-base compounds were initially prepared by condensing dimedone

3,4-Diacetyl-2,5-hexanedione (tetraacetylethane) is a tetradentate dibasic ligand and constitutes two acetylacetone molecules linked together through the central carbon. The ligand is thus capable of coordinating two metal cations. Its reaction with
