合成了8族（6，Ru Ⅱ）和10族（7和8，Ni Ⅱ和Pt Ⅱ）金属的π共轭三核二硫杂环戊烯.化合物6和7在金属二硫杂环戊烯环的氧化过程中通过三个二硫杂环戊烯部分之间的亚苯基桥表现出强烈的电子通信，这在第9族金属1-5的类似家族中尚未得到证实。化合物8在可见光和近红外区有一个强的吸收带，与单核配合物的相应吸收带相比，该吸收带发生了红移和展宽，被认为是二亚胺的电荷转移。
New π-conjugated trinuclear dithiolenes with group 8 (6, RuII) and 10 (7and8, NiIIand PtII) metals were synthesized. Compounds6and7exhibited intense electronic communication through the phenylene bridge among the three dithiolene moieties during oxidation of the metalladithiolene rings, which has not been confirmed in the analogous family of group 9 metals,1–5. Compound8exhibited an intense absorption band across the visible and near-IR regions, which was assigned as a charge transfer to the diimine and was red-shifted and broadened compared to the corresponding band of the mononuclear complex.
