We report the first crystal structures of aniline complexes of silver, namely the three aniline-complexed silver(I) disulfonylamides 1 (aniline)(dimesylamido)silver(I), 2 bis(aniline)(1,1,3,3-tetraoxo-1,3,2-benzodithiazolido)silver(I) and 3 bis(aniline)silver(I) [di(p-bromobenzenesulfonyl)amide] : aniline (1:1). Compound 1 is molecular, with approximately linear coordination at silver; the coordination is extended to T-shaped by an Ag···O contact of 2.7136(11) Å to a neighbouring molecule related by a axis translation. Compound 2 is molecular, with trigonal planar coordination geometry at silver. Compound 3 is ionic, with exactly linear coordination at each of the two independent silver atoms, both of which occupy inversion centres; the third aniline is not coordinated to the silver atoms. Classical hydrogen bonds are the main feature of the packing diagrams for all three compounds. The packing of 1 and 2 can be analysed in terms of hydrogen-bonded dimers, further linked to form ribbons parallel to the a axis. In 3, the cations and anions are linked to form zigzag chains parallel to the b axis, and these are further linked to form a layer structure parallel to (001). The free aniline molecules are hydrogen bonded above and below the layer.
