Abstract

A dimeric gold(III) complex, the 18‐membered ring system 1, is formed on treatment of Na[AuCl₄] 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]. (Figure Presented.)
