Chemical and electrochemical synthesis, structure and magnetic properties of mono- and binuclear 3d-metal complexes of N-[2-[(hydroxyalkylimino)methyl]phenyl]-4-methylbenzenesulfonamides

摘要

Complexes of Cu(II), Ni(II), Co(II) and Fe(II) ions with N-[2-[(hydroxyalkylimino)methyl]phenyl]-4-methylbenzenesulfonamides containing the (CH2)(n)-spacer of a variable length (n = 2-6) were synthesized by chemical and electrochemical methods. All the compounds were characterized by C,H and N elemental analysis, IR, EPR and X-ray absorption spectroscopy data. The dimeric structures of the copper complexes with (CH2)(n)-spacers (n = 2,3) were determined by the magnetochemical method and by X-ray diffraction analysis for the copper complex with the (CH2)(3)-spacer.
