Description
Summary:The reaction of [Ru(bpy)(tpy)(Ipcyd)]+ (bpy = 2,2′‐bipyridine, tpy = 2,2′:6′,2′′‐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)}(BPh4)2]· 4(PhCH3) (dcpeb = dicyanamidophenylethynylbenzene dianion). The crystal structure data are as follows: crystal system monoclinic, space group P21/c, with a = 12.6960(3), b = 34.0960(10), c = 15.3540(4) Å, β = 110.7381(15)°, V = 6215.8(3) Å3, and Z = 2. The structure was refined to a final R factor of 0.063. The metal ions are separated by a through‐space distance of 24.9 Å. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
