title: Crystal structure of [Ag(NH3)3]2[Ag(NH3)2]2[SnF6]F2, a compound showing argentophilic inter-actions.
abstract: Bis[triamminesilver(I)] bis-[diamminesilver(I)] hexa-fluorido-stannate(IV) difluoride, [Ag(NH3)3]2[Ag(NH3)2]2[SnF6]F2, was obtained in the form of colourless crystals from the reaction of CsAgSnF7in anhydrous ammonia. Two different ammine complexes of silver(I) are present in the structure,i.e.a linear diammine and a T-shaped triammine complex. The ammine silver(I) complexes show Ag⋯Ag distances in the range of argentophilic inter-actions. In the crystal, several N-H⋯F hydrogen bonds are present between the complex cations and the SbF6-and F-anions, leading to the formation of a three-dimensional network.
