Synthesis And Characterization Of Monodentate-coordinate Manganese(Ⅱ) Complexes With Schif Bases Containing Adamantyl Group

Transition metal complexes with Schiff bases were found exhibiting biological activity,electrochemical property and magnetic property because of their specific structures.In this thesis,six Schiff bases with adamantyl group and the corresponding manganese complexes were synthesized and characterized.The structures of the compounds were deduced.One ligand and four complexes were analyzed by X-ray single crystal diffraction.Meanwhile,four complexes were tested by means of the magnetic susceptibility.The following main work,1.The reactions of manganese（II）chloride tetrahydrate and six Schiff base ligands derived from amantadine（or rimantadine）and salicylaldehyde（or substituted salicylaldehyde）generated six novel complexes,C₃₄H₄₂Cl₂MnN₂O₂（1）,C₃₆H₄₆Cl₂MnN₂O₄（2）,C₃₈H₅₀Cl₂MnN₂O₂（3）,C₄₀H₅₄Cl₂MnN₂O₄（4）,C₃₆H₄₆Cl₂MnN₂O₄（5）and C₄₂H₆₀Cl₂MnN₄O₂（6）,respectively.2.The compounds were characterized by IR,melting point,elemental analysis,molar conductance and ¹H NMR.3.The single crystals of one ligand and four complexes were obtained by solvent evaporation method.Their structures were revealed by single crystal X-ray diffraction.4.Four complexes were tested by means of the magnetic susceptibility,and their magnetic behavior was analyzed.
