Crystal structure of [Ag(NH3)(3)](2)[Ag(NH3)(2)](2)[SnF6]F-2, a compound showing argentophilic interactions

Bis[triamminesilver(I)] bis[diamminesilver(I)] hexafluoridostannate(IV) difluoride, [Ag(NH3)(3)](2)[Ag(NH3)(2)](2)[SnF6]F-2, was obtained in the form of colourless crystals from the reaction of CsAgSnF7 in 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 center dot center dot center dot Ag distances in the range of argentophilic interactions. In the crystal, several N-H center dot center dot center dot F hydrogen bonds are present between the complex cations and the SbF6- and F- anions, leading to the formation of a three-dimensional network.
