 Title    Gold(I) Complexes of Secondary and Tertiary Amines. Crystal Structure of Triphenylphosphineaurio(I)quinuclidinium Tetrafluoroborate  
 Abstract    The secondary amine piperidine and the tertiary amine quinuclidine (l-azabicyclo[2.2.2]-octane) were reacted in TH F with one equivalent of triphenylphosphinegold(I) tetrafluoro­ borate, [Ph3PAu]+ BF4", to give the m onoaurated ammonium salts of formula [R"NHp_")AuPPh3]+ BF4~ (n = 2, 3). The compounds were obtained as crystalline solids in good yields, and were characterized by IR and N M R spectroscopy as well as mass spectrom ­ etry and elemental analysis. The crystal structure of the quinuclidinium salt was determined (space group Pbca, Z = 8). The analysis shows independent formula units with no intermolec­ ular Au---Au contacts. The A u (I)-N bond (2.11(1) Ä) is significantly longer than the average value found in poly-aurated ammonium salts.
