<![CDATA[New complexes compounds of some metal ions such as [VO(IV)), Co(II) Ni(II),Cu(II),Zn(II) and Cd(II)] are synthesized with ( 2-(((5-(3, 5-dinitrophenyl)-1, 3, 4-thiadiazol-2-yl-2,5dihydroxy benzalidine. The ligand Schiff base was synthesized by condensation of 2-amino -5-(3,5dinitro phenyl )1,3,4-thiadiazole with 2,5dihydroxy benzaldehyde .The suggested structures of new complexes are characterized by elemental micro analysis (C.H.N), FT-IR, UV-Vis spectra, Thermal gravimetric analysis (TGA-DTA), flame atomic absorption, molar conductivity, magnetic susceptibility and Mass Spectra. The suggested theses complexes according to the results data the probable coordination geometries are octahedral complexes excepted C1 was pyramidal. The all complexes were found to be non-electrolyte.Keywords: 1, 3, 4-thiadiazole, Schiff base and metal ions]]>
