Synthesis and Characterization of Novel Bidentate Ligand type NO and Its Complexes with (CoII , NiII ,CuII and ZnII).

      The [2-aminobenzothiazole]was reacted with [2,4,6 triyhydroxy-acetophenon monohydrate] to give a new ligand [2-N-2,4,6-trihydroxyacetophenonyliden benzothiazole] [H₃L]. This   ligand  was  reacted  with metal ions  ( Co^II, Ni^II,Cu^II  and Zn^II)  in methanol as solvent   with ( 1:2 ) metal : ligand  ratio to  give a series of  new  complexes   with  general formula [ M(H₂L)₂],(where:M= Co^II, Ni^II ,Cu^IIand, Zn^II).All compounds were characterized by spectroscopic methods ( I.R , U.V – vis,HPLC) atomic absorption, along with chloride content  and    conductivity  measurements. According to  the  data  of these  measurements   we suggested a tetrahedral  geometry    for (Co^II, Ni^II,Cu^II, and, Zn^II ) complexes.
