Abstract
This research including preparation new derivatives for heterocyclic compounds are (1,3 benzothiazole), process synthesis in us research divided into two major pathways: First , synthesis 2- amino benzothiazole derivatives ethyl 2-aminobenzo[d]thiazole-6-carboxylate (HL).Second pathway ,reaction of salicyldehyde and saccharin with amine group of benzothiazole (HL) produced of Schiff's base compounds(HL 1 ,HL 2 ). The compound was characterized by FT-IR, UV-Vis and 1 H, 13C -NMR spectra. The complexes of the bivalent ions (M +2 =Co, Ni, Cd and Hg) with Schiff bases derived to give ligands (HL 1 , HL 2 ) were prepared and then reacted with metal salts in ethanol as a solvent in (1:2) ratio (M: L). the complexes which have the general formula [M (HL n ) 2Cl2 ] when (n=1, 2). Have been prepared and characterized by FT-IR, UV-Vis spectra, conductivity measurements, magnetic susceptibility. The proposed geometrical structures for all complexes were octahedral. Keywords : ligand, Benzothiazole , Salicyldehyde , Saccharin , Schiff bases, Complexes.
