SYNTHESIS AND STUDY OF SOME TRANSITION METAL COMPLEXES WITH MANNICH BASE DERIVED FROM 2HYDROXY 1, 3, 4-TRIAZOLE-5-THIONE

Abstract

A new Mannich base N,N-di{4-(2-hydroxy-1,3,4-triazole-5-thione)-Methyl}.Amino benzothiazole (HL) have been prepared by condensation reaction of formaldehyde,2-aminobenzothiazole & 2-hydroxy -1,3,4-triazole -5-thione.The new ligand has been characterized by spectroscopic techniques (F.T.I.R, UV-Visible), micro, analytical (C.H.N).The new base have been used as ligand to prepare a number of complexes with Ni(II), Cu(II), Pd(II), Zn(II), cd(II) and Hg(II) ions. The new metals complexes have been fully characterized by physical properties, melting point, molar conductance in 10-3 M of (D.M.S.O).Mea surements of magnetic moments µeff. (B.M), as well as the spectroscopic measurements (F.T.I.R and UV-Visible).More ever the anti-bacterial activity of the complexes were estimated and compared with that of free ligand by using diffusion method.
