✦ Synopsis

The reaction of [Ru(bpy)(tpy)(Ipcyd)] + (bpy = 2,2Ј-bipyridine, tpy = 2,2Ј:6Ј,2ЈЈ-terpyridine, Ipcyd = 4-iodophenylcyanamide anion) with diethynylbenzene in a Sonogashira cross-coupling reaction gives an unprecedentedly long and conjugated dinuclear complex [{[Ru(bpy)(tpy)] 2 (µ-dcpeb)}(BPh 4 ) 2 ]• 4(PhCH 3 ) (dcpeb = dicyanamidophenylethynylbenzene dianion). The crystal structure data are as follows: crystal sys- [a] CEMES-
