Abstract

4-N,N-dimethylaminobenzoic acid complexes of Mn II , Co II , Ni II and Cu II were synthesised and their structuralproperties were investigated by employing elemental analysis, magnetic susceptibilitiy, solid state UV-vis, directinjection probe mass, FTIR and thermoanalytic TG-DTG methods.According to the microanalytical results, formulaof complexes are CMn, C H NO H NOCo, CNi and CH NO H NOCu. The complexes of Mn II and Ni II contain four moles of coordination waters, but Co II and Cu II complexes have two moles of coordinatedwater ligands. All of the complexes include two moles 4-N,N-dimethylaminobenzoate ligands, but it was coordinatedto metal atom as monodentate in Mn II and Ni II and bidentate in Co II and Cu II complexes.It was found that ratioof metal:ligand is 1:2 and the decomposition of each complex starts with dehydration and follows by decompositionof organic part, respectively. The thermal dehydration of the complexes takes place in steps from one to two. Thedecomposition mechanism and thermal stability of the investigated complexes are interpreted in terms of theirstructures. The final decomposition products are found to be the respective metal oxides
