A new dithiolene ligand with 3,5-dibromo substituted phenyl groups was designed and synthesized. The protected form of the ligand was reacted with a nickel salt providing neutral Ni(S(2)C(2)(3,5-C(6)H(3)Br(2))(2))(2) and anionic Ni(S(2)C(2)(3,5-C(6)H(3)Br(2))(2))(2) isolated as a Bu(4)N(+) salt. Both were characterized by UV-visible and IR spectroscopy and compared with the similar known molecular systems. They exhibit intense low-energy transitions that are characteristic of such systems. The electrochemical behavior of these molecules was investigated by cyclic voltammetry.
设计并合成了一种带有3,5-二溴取代苯基的新型二硫纶配体。该配体的保护形式与镍盐反应,得到中性的Ni(S₂C₂(3,5-C₆H₃Br₂)₂)₂和以Bu₄N⁺盐形式分离得到的阴离子[Ni(S₂C₂(3,5-C₆H₃Br₂)₂)₂]⁻。二者均通过紫外可见光谱和红外光谱进行了表征,并与类似的已知分子体系进行了比较。它们表现出此类体系特有的强烈低能量跃迁。通过循环伏安法研究了这些分子的电化学行为。
