Synthetic & Analytic Study of Complexes of Some Transition Elements with 5-Phyenyl Amino-3-Salicylidimino- 1,2,4 Thiadizole

Abstract

The new Schiff base 5-phyenyl amino-3-Salicylidimino- 1,2,4 thiadizole (HL) was prepared from condensation reaction of 3-amino-5-phenyl amino-1,2,4-thiadiazole with salicyldehyde. Complexes with some selected metal ions Cr(III) ,Fe(III), Zr(IV), pd(II) and pt(IV) were prepared by reacting the ligand with the hydrated metal chlorids CrCl3.6H2O , FeCl3.6H2O , ZrOCl28H2O , PdCl2 ...and K2PtCl4. 2H2O in the presence of 5% triethyl amine solution Et3N. The elemental analysis (C.H.N.M), electronic spectra (Uv-Vis spectra) showed that molar ratio of metal : ligand was 1:2. The F.T.I.R. spectra , Molar conductivity ( Λm ) and magnetic susceptibility of complexes were also determined .
