Synthesis and Characterization of New (2-(((5-(3, 5-Dinitrophenyl)-1, 3, 4-Thiadiazol-2-yl-2,5 Dihydroxy Benzalidine))) Metal Complexes

Abstract

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
