Figure 7
Crystal structures of the (a,b) LT and (c,d) HT polymorphs of 2NICz viewed down (a,c) [100] and (b,d) [001]. Atom colours as in Fig. 4. The 2LT and 2HT polymorphs of 2,5NICz are isostructural and not shown. Ellipsoids are drawn at the 50% probability levels. Crystallographic symmetry elements are indicated by the common graphical symbols (Hahn & Aroyo, 2016). |
