Figure 3
(a) The overall packing diagram of (I), showing a layered arrangement of cations and anions (cations in grey). (b) Two layers are shown, where the cations from each are further connected to each other parallel to the a axis via an aryl–aryl face-to-face motif (π–π stacking) (viewed down the crystallographic c axis). One layer is shown in black and the other in grey. Intermolecular interactions are indicated by dotted lines. |
