The reaction of 2.4,6-trihydroxyactophenonemonohydrate with hydrazine nionohydrate was realized under reflux in methanol and a few drops of glacial acetic acid were added to give the 2-(l-hydrazono-ethyl)-benzene-1.3.5-triol, which reacted with لا4بل؛ ligand (قنقل<، salicylaldehyde in methanol to give a new type -3,5,؛f(2-{l-[(2-hydroxy-benzyHdene)-hydrazono]-ethyl}benzene-l triol .

The ligand was reacted with McS (where M=Co, Ni, Cu, and Zn) under reflux in methanol with (1:1) ratio to give complexes of the All compounds have been ' .لراقا-ا) ١^] general formula by spectroscopic methods [1H NMR, 1R، U.V-Vis, HPLC, atomic absorption] microanalysis along with conductivity measurement.
