| Abstract | ||
| A new complexes of some transition metal ions (Co(II), Ni(II), Cu (II) and some non-transition metal ions Zn(II), Cd(II), Hg(II) with two multidentate ligands 2-acetamidothiazole (at) and 2-acetamidobenzothiazole (abt). All the prepared complexes have been characterized by elemental analysis, Molar conductance, Magnetic susceptibility infrared and electronic spectral. The complexes were classified as: 1- When the ligands (at and abt) behave as Mondentate coordinated throughnitrogen of thiazole ring, the resulting complexes are of the type [ML3X3] (M=Cr+3 when L= abt and at) (M=Fe+3 when L= abt,at). 2- When the ligands (at and abt) behave as bidentate coordinated through nitrogen of thiazole ring and nitrogen of amide or oxygen of the carbonyl, the resulting complexes are on the type [Co(abt)2.Cl.H2O]Cl.H2O, [ML2Cl2] (M=Mn+2 ,Zn+2,Hg+2when L= abt and at), [ML2.(H2O)2](NO3)2 (M=Cr+3 when L= abt and at; M=Ni+2 when L=abt) and [CdL2](NO3)2 (L=abt and at). 3- When the ligands (at and abt) behave as tridentate coordinated through the nitrogen of the thiazole ring and nitrogen of amide and the oxygen of the carbonyl group. The resulting complexes are on the type [Cu(abt)2] (NO3)2. The prepared complexes have octahedral structures except the complexes of type [CdL2] (NO3)2 have tetrahedral structures. | ||
