The reaction of equivalent quantities of (triphenylphosphine)gold chloride and silver fluoride in CH 2 Cl 2 /MeOH gives tris[(triphenylphosphine)gold(I)]oxonium dihydrogentrifluoride in good yield. This product is formed through the action of water in the reaction medium. Crystals of {[(Ph 3 P)Au) 3 O} -  [H 2 F 3 ] -  1.5 CH 2 CI 2  (monoclinic, space group P2 1 /c, Z = 4) contain the cations as hexanuclear dimers with short intra- and intermolecular Au-Au contacts. The structural details are similar to those of related salts with different anions. The [H 2 F 3 P anion is V-shaped with one symmetrical and one unsymmetrical F-H-F hydrogen bond and is best described as an addition compound of an HF molecule and a [F-H-F] -  anion. The results indicate a high affinity of H 2 O/OH -  for (phosphine)gold fluorides and - by the same token - prove that tri(gold)oxonium cations are stable to anhydrous HF and F -  anions. By contrast, hydrochloric acid is known to degrade {[(R 3 P)Au] 3 O} +  affording (R 3 P)AuCl and water.
