الملخص العربي
A new ligand [1-(ortho hydroxy-benzylidene),2-Sodium pyruvalidene hydrazine] [NaHL] was prepared and its complexes (Co(II), Ni(II), Cu(II), and Zn(II)). This ligand was prepared in two steps. The first step a solution of salicyladehyed in methanol react under reflux with hydrazinemonohydrate to give an (intermediate compound) [(1-ortho hydroxy benzylidene) hydrazine] which react in the second step with Sodium pyruvate giving the mentioned ligand. The complexes were synthesized in direct reaction of the corresponding metal chloride with the ligand. The ligand and complexes have been characterized by spectroscopic methods (IR, UV-Vis, atomic absorption), chloride content and conductivity measurement. The obtained data propose a chemical formula [M (L)] and geometries structure as a tetrahedral distorted about metal ion for the studied complexes.
