摘要：

Two iron(III) complexes with the terdentate ONS and ONN ligands benzoylacetone thiosemi- and S-methylisothiosemicarbazone, respectively, of the general formula [Fe(HL)Cl2], were synthesized. Besides, the iron(III) complexes of the general formula [Fe(L)Cl] involving the quadridentate ONNO ligands N(1)-benzoylisopropilidene-N(4)-salicylidene (5-chloro-, 3,5-dichloro-, or 5-nitro-salicylidene) S-methylisothiosemicarbazide were also prepared. The complexes were characterized by elemental analysis, molar conductivity and magnetic measurements, IR and electronic spectra, as well as by cyclic voltammetry. It was found that the complexes are high-spin pentacoordinated. In addition, a detailed voltammetric study in DMF solutions has shown that the electrochemical processes are frequently accompanied by various chemical reactions.
