Figure 3
The crystal structure of (I), viewed along the a axis. Dashed lines show C—H⋯Cg1 and Cg2⋯Cg2 interactions. Only H atoms participating in hydrogen bonding are shown. Cg1 and Cg2 are the centroids of the rings defined by atoms C1–C6 and N5/C8–C12, respectively. [Symmetry codes: (iii) x − , −y + , z; (iv) −x, −y + 1, −z.] |
