Abstract

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)(2) (2) and Fe(Me(2)pipto)(3)(2) (4) complexes, which show significant differences when compared with the corresponding reaction products when using Me(2)pipdt.

摘要

讨论了新型硫-氧供体配体 Me(2)pipto（1）的结构和电子特性，并与相应的二硫代配体 Me(2)pipdt 进行了比较。通过配体的供电子原子的软硬性质，实现了对配体的电子和配位性质的调节。通过 Ni(II)和 Fe(III)阳离子配位性质的检查，得到了Ni(Me(2)pipto)(3)(2)（2）和Fe(Me(2)pipto)(3)(2)（4）两种配合物，与使用 Me(2)pipdt 时的相应反应产物相比，它们有明显的差异。
