SYNTHESIS, MAGNETIC AND SPECTROSCOPIC STUDIES of Ni(II), Cu(II), Zn(II) and Cd(II) COMPLEXES OF A NEWLY SCHIFF BASE DERIVED FROM 5-BROMO- 2-HYDROXYBEZYLIDENE)-3,4,5-TRIHYDROXYBENZOHYDRAZIDE)

چکیده
A new hydrazide Shiff base ligand GHL1 (5-bromo-2-hydroxybezylidene)-3,4,5trihydroxybenzohydrazide) was prepared by refluxing of trihydroxybenzhydrazide with an ethanolic of 5-bromo2-hydroxybenzaldehyde. The ligand reacted with Ni(II), Cu(II), Zn(II) and Cd(II) (acetate salts). All the complexes were characterized by elemental analysis, molar conductivity, TGA, UV-Vis and FT-IR spectral studies. All the complexes have octahedral geometry except Ni(II) complex which has tetrahedral geometry.
