Figure 1
The coordination of the Cs+ cation by nine oxygen atoms and one nitrogen atom of six different bistriflimide anions coordinating above and three below, in a view slightly off the (100) plane. Other caesium cations are crystallographically equivalent to Cs1, and are shown to depict how the sheet extends. The displacement ellipsoids are drawn at the 50% probability function with the color scheme of caesium (purple), oxygen (red), sulfur (yellow), nitrogen (blue), carbon (black), and fluorine (green). |
