Synthesis and Characterization of Cu(II), Ni(E), Cd(II) and Zn(II) with Salicylaldehyde-1H- Benzotriazol-1-Aceylhydrazone and 2-Hydroxy- Naphthylaldehyde-1H- Benzotriazol-1-Aceylhydrazone

Two new ligands, salicylaldehyde- 1H-benzotriazol-1- acctylliydrazone and 2-hydroxy-naphthylaldehyde-1H-benzotriazol-1-acetyihydrazone have been synthesized and used in preparing some metal(II) complexes. Attempts have been made to ascertain their probable structures on the basis of elemental analyses, molar conductivities, IR, 1 H NMR, TGA, UV and iluorescence spectra. It is suggested that the complexes have a four-coordinated, square-planar, dimer configuration. The IR and 1 H NMR spectral data indicate that the ligands behave as dinegative, tridentate species in the dcprotonated complexes.
