摘要：

A dimeric gold(III) complex, the 18-membered ring system 1, is formed on treatment of Na[AuCl4] with the potentially chelating ligand 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].
