The synthesis of some new coordination compounds for cobalt (II), nickel(II)and copper(II)with Schiff bases derived from(2-aminobenzothiazole,6-nitro-2aminobenzothiazole,4,6-dibromo-2-aminobenzothiazole) and 4-N-dimethylbezaldehyde to give ligands (La,Lan and Ladb) were prepared and then reacted with metal salts in ethanol as a solvent in 1:2 ratio (metal : ligand). The complexes which have the general formula [ML2Cl2] Where M=Co (II) , Ni (II) and Cu (II),( L=La,Lan,or Ladb) all ligands and it's metal complexes were characterized using metal analysis by Atomic absorption, Infrared spectra ,Electronic spectra, Molar conductance and Magnetic moment measurements ; These measurements indicated that the ligands coordinate with metal (II) ion in a bidentate manner through the nitrogen atoms in ligands, Octahedral structures were suggested for metal complexes. Introduction Schiff bases derived from an amine and aldehyde are an important class of ligands that coordinate to metal ions via azomethine nitrogen and have been studied extensively(Arora & Sharma,2003;Vigato & Tamburini,2004 and Katsuki,1995). These complexes are play an important role in the development of coordination chemistry( Sousa et al.,2003;Kou et al.,2004). Thiazole derivatives have been found a number uses in medicinal and pharmaceutical fields(Malik & Rajeev,1982). Some of them have been showed to have antitumer activity(Bradshaw ,2002;Ioaizaperez,2002 and Racane,2006)anticandidous(Sidoova et.al,1997)Parkinson ' s disease (Alain et.al,1997) antihistaminic and antiflammatory (Abignente et.al,1983).Benzothiazole have also shown significant effect against cancer (Swarnkar et.al, 2007)and antibacterial agent (Lednicar & Matcher,1997; Karia & Parsania,1999) .Another area of application of these Schiff bases is analytical chemistry where some of compounds were used as ligand in complexometry topic (Rodriguez et.al,2004) and catalysts as a corrosion
