(a) The molecular tapes in (I) generated by N3–H3⋯O4i hydrogen bonds and by weak C11—H11B⋯O2ii and C12—H12A⋯O2ii hydrogen bonds. C6—H6⋯N13iv hydrogen bonds connect the tapes. Hydrogen bonds are indicated by dotted lines. [Symmetry codes: (i) −x + 1, −y + 2, −z; (ii) −x + 1, + y, − z; (iii) −x + 2, + y, − z.] (b) The molecular tapes in (I), expanded along the c axis. A sinusoidal conformation of the tapes is shown. Hydrogen bonds are indicated by dotted lines. |
