Gold(I) complexes with amine ligands, II. Methylpyridine complexes of gold(I) [German]

摘要

Gold(I) complexes of overall formula LAuCI (L = various methylpyridines) are non-conducting in acetone. X-ray structure analyses show that the solid state structure of the cor responding complex 1 (L = 7-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 Au ... Au contacts, leading to chains of gold atoms; additionally, complexes 3 and 4 show weak Au ... F contacts. The (3-picoline)gold(III) complex trans-(L2AuCl2)(+)(SbF6)(-) (5) was obtained as a by-product; it too contains short Au ... F contacts. [References: 23]
