Abstract :Four new azo dyes, L1, L2, L3, and L4, were prepared by linking benzaldehyde p-aminobenzoylhydrazone insert ignore into journalissuearticles values(3); and p-hydroxybenzaldehyede p--aminobenzoylhydrazone insert ignore into journalissuearticles values(4); to barbituric acid and 1,3-dimethylbarbituric acid through diazo-coupling reactions. Reactions of the azo-dyes with copper chloride and bidentate ligand, 1,10-phenanthroline, produced mixed-ligand dinuclear complexes with general stoichiometry [Cu2Linsert ignore into journalissuearticles values(phen);2]Cl2 insert ignore into journalissuearticles values(7, 8, 9, and 10);. The structures of both azo dyes and their complexes were identified by elemental analyses, FT-IR, 1H-NMR, UV-VIS, magnetic susceptibility, and mass spectral data.
