چکیده
Structural and electronic features of the novel title sulfur-oxygen donor ligand Me(2)pipto (1), are discussed in comparison with those of the corresponding dithione ligand Me(2)pipdt. A tuning of the electronic and coordination properties of the ligand, relatable to the soft/hard power of the donor atoms, is achieved. Coordination properties have been checked towards Ni(II) and Fe(III) cations obtaining [Ni(Me(2)pipto)(3)](BF(4))(2) (2) and [Fe(Me(2)pipto)(3)](BF(4))(2) (4) complexes, which show significant differences when compared with the corresponding reaction products when using Me(2)pipdt.

Four new [NiH2L](ClO4)2 (1), [CuH2L](ClO4)2 (2), [MnH2L](ClO4)2 (3) and [CdH2L](ClO4)2 (4), complexes were prepared by the reaction of a new Schiff base ligand and Cu(II), Ni(II), Mn (II) and Zn (II) metal ions in equemolar ratios. The ligand, H2L was synthesized by reaction of 1, 4- bis (2- formylphenyl) piperazine and ethanol amine and characterized with IR and 1H,13C NMR spectroscopy. All co...

متن کاملSynthesis, characterization, DFT calculations, and electrochemical comparison of novel iron(ii) complexes with thione and selone ligands.
Thione- and selone-containing compounds and their metal complexes show promise as antioxidants, as antithyroid drugs, and for applications in lasers and blue light-emitting diodes. Although Cu(i/ii), Co(ii), Ag(i), and Zn(ii) coordination to thione and selone ligands has been broadly studied and Fe(ii) plays an important role in oxidative damage, very few iron-thione complexes and no iron-selon...
