The complexes were characterized by elemental analysis, direct injection probe mass, IR, <sup>1 </sup>H-NMR, <sup>13 </sup>C-NMR, UV-vis, ESR spectroscopy, thermogravimetry measurements. Concequently, it has been determined that Complex 4 have square-pyramidal and the others complexes have octahedral geometries. The decomposition of each complex starts with dehydration and follows by decomposition organic part, respectively.The thermal dehydration of complexes takes place in steps from one to two. The decomposition mechanism and termal stability of the investigated complexes are interpreted in terms of their structures.The final decomposition products are found to be the respective metal oxides. </p>}, number={2}, publisher={Sakarya University}
