Figure 6
The packing diagrams of (a) (I) and (b) (II), viewed along the b axis. For clarity, H atoms not involved in molecular interactions have been omitted in part (a) and all H atoms have been omitted in part (b). The additional phenyl ring available in (II), which is in the equivalent position of the H atom of N—H in (I), is shown in green. (c) Superposition of (I) with the CSD structures (refcodes BIFXIA_Mol1 and BIFYUN). Both BIFXIA_Mol1 and BIFYUN adopt similar conformations to compound (I). The two structures contain a six-membered ring instead of the seven-membered ring present in (I). (d) The molecular packing diagram of BIFYUN, viewed along the a axis. The N—H⋯O hydrogen-bond pattern of (I) shown in part (a) is similar to that in BIFYUN. |
