Gold(I)-Komplexe mit Aminliganden, II [1]. (Methylpyridin)-Komplexe von Gold(I) Gold(I) Complexes with Amine Ligands, II. Methylpyridine Complexes of Gold(I)

Gold(I) complexes of overall formula LAuCl (L = various methylpyridines) are non-con­ ducting in acetone. X-ray structure analyses show that the solid state structure of the cor­ responding complex 1 (L = 2-picoline) is molecular; the 3-picoline derivative 2 is however ionic (L2Au)+(AuCl2). 3-Picoline forms a molecular complex LAuC6F5 (3) and also the ionic (L2Au)+(SbF6)_ (4). Complexes 1, 2 and 4 display short A u--A u contacts, leading to chains of gold atoms; additionally, complexes 3 and 4 show weak A u F contacts. The (3-picoline)gold(III) complex /rans-(L2AuCl2)+(SbF6)_ (5) was obtained as a by-product; it too contains short A u F contacts.
