A dimeric gold( III ) complex , the 18‐membered ring system 1 , is formed on treatment of Na[AuCl 4 ] with the potentially chelating lig‐and 6‐(2‐thienyl)‐2,2′‐bipyridine (HL). Metalation of the thienyl unit occurs in the 5‐position, and the coordination sphere of gold also includes two trans Cl ligands and an N atom from the terminal pyridine of the second HL ligand. In contrast, Pd II and Pt II form cyclometalated complexes of the type [MLCl].
