A novel,simple approach to the synthesis of macrocyclic Schiff base ligand bearing pendent coordinating groups is described and its 1∶1 inclusion complexes are prepared and characterized.The composition of the title material was determined by the chemical and spectroscopic methods and the surrounding of metal with the octahedral structure for the all complexes was suggested.The data reveal that the ligand acts as O2N4 hexadentate structure with each metal atom in an octahedral environment.Infrared and 1HNMR spectra of the complexes agree with the coordination to the central metal atom.The stability constants of the complexes are calculated spectrophotometrically.The activation kinetic and thermodynamic parameters are calculated in different stages of thermal decomposition using the conjugate residual method (CR method).Moreover,the ligand and its metal complexes are screened against bacteria and fungi using the inhibitory zone diameter.The effect of a neutral chelating ligand on the complexation with iron in different types of natural water was studied by using recovery test.
