Syntheses, Crystal Structuers And Spectral Properties Of Asymmetrical Salamo Ligands And Co(?)?Ni(?) And Zn(?) Complexes

Salen-type complexes and their derivatives not only show a variety of properties in catalytic, but also have some advantages in the field of antibiosis, treatment of tumors, Bio inspired oxygen and so on. Supramolecular were formed metal complexes by hydrogen bonding, ?-? stacking interaction and C-H���? interaction, which show the feature of ion recognition, catalysis, photoelectric properties, magnetic properties and so on. Therefore, it is quite important to design and synthesis Salen type complexes and their derivatives.In this paper, two kinds of diamines, 1, 2-bis?aminooxy?ethane and 1,3-bis?aminooxy?propane are synthesized at first. Three new ligands and eight complexes are obtained by two kinds of diamines and 4-Methoxysalicylaldehyde, salicylaldehyde,3,5-dichloro-salicylald-ehy de,5-chlorosalicylaldehyde and 4-?N,N-diethylamine?-2-hydroxybenzaldehyde,which were characterized by IR, UV-Vis, fluorescence spectra and point melting, elemental analysis,solubility measurement and a series of physical and chemical analysis methods.{?CoL¹?₂??-OAc?₂Co}�CH₂Cl₂,[{NiL¹?C₂H₅OH?}₂??-OAc?₂Ni]�2C₂H₅OH,{?ZnL¹?₂??-OAc?₂Zn},[{NiL²?MeOH?}₂??-OAc?+2Ni]�2Me OH,[{NiL²?C₂H₅OH?}₂??-OAc?₂Ni]�2H₂O,[{NiL²?C₃H₇OH?}₂??-OAc?₂Ni]�2H₂O,[{NiL²?C₃H₇OH?}₂??-OAc?₂Ni]and[{NiL²?C₄H₉OH?}₂??-OAc?₂Ni]�2C₄H₉OH are obtained by natural evaporation of the solvent method in various solvent systems. They are obtained using three new ligands and Co?OAc?₂�4H₂O, Ni?OAc?₂�4H₂O and Zn?OAc?₂�2H₂O. Crystal structure, chemical composition and space group are determined by using X-ray diffraction method.
