Figure 5
A perspective view of (Ib), showing the atom-numbering scheme. Part (a) contains 6-chloroisocytosine molecules A to F, 2-aminopyridine P and the disordered AHP molecule R/S, and part (b) contains 6-chloroisocytosine molecules G to M and 2-aminopyridine molecule O. In both parts, displacement ellipsoids are drawn at the 50% probability level and hydrogen bonds are displayed as dashed lines. |
