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 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?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.
