examples of metal dithiolenes belonging to the class [M(R-dmet)(2)] [R-dmet = formally monoreduced N-substituted thiazolidine-2,4,5-trithione; R = Et, M = Ni (1), Pd (2), Pt (3)]. A comparative spectroscopic, electrochemical, and density functional theory theoretical investigation indicates that [M(R-dmet)(2)] complexes show features intermediate between those of the dithiolenes belonging to the previously
我们报道了属于类[M(R-dmet)(2)]的金属二硫代苯酚的第一个实例。[R-dmet =形式上单还原的N-取代的噻唑烷-2,4,5-三硫酮;R = Et,M = Ni(1),Pd(2),Pt(3)]。比较光谱学,电化学和密度泛函理论理论研究表明[M(R-dmet)(2)]配合物显示的特征介于介于先前报道的[M(R,R'-timdt)类的二硫代菲林之间(2)]和[M(dmit)(2)](R,R'-timdt =正式单还原的N,N'-二取代的咪唑烷-2,4,5-三硫酮; dmit = 2-thioxo-1,3-二硫代4,5-二硫代拉托)。在1和3上进行的UV-vis-near-IR光谱和循环伏安法/微分脉冲伏安法测量证明,新的二硫代己烯具有稳定的中性,单阴离子,
