π共轭三核铱和钴二硫纶分别与Co（2）（CO）（8）和Fe（CO）（5）形成多金属-金属键，分别得到Ir（3）Co（6）九核和Co（3）Fe（3）六核簇合物5和6。5保留了平面的骨架和强烈的π共轭跨越三个iridadithiolenes和亚苯基桥，这导致强烈的电子通信之间的三个Co（2）（CO）（5）单元在还原混合价态。
π-Conjugated trinuclear iridium and cobalt dithiolenes undergo multiple metal-metal bond formation with Co(2)(CO)(8) and Fe(CO)(5), giving rise to Ir(3)Co(6) nonanuclear and Co(3)Fe(3) hexanuclear cluster complexes 5 and 6, respectively. 5 retains a planar framework and intense π conjugation across the three iridadithiolenes and the phenylene bridge, which results in intense electronic communication among the three Co(2)(CO)(5) units in reduced mixed-valent states.
