Figure 2
The packing of the molecules of (I), viewed along the b axis. Hydrogen bonds are drawn as dashed lines (in the electronic version of the journal, blue dashed lines indicate weak inter-chain hydrogen bonds). Only H atoms participating in hydrogen bonds are shown. [Symmetry codes: (iii) −x + 2, y + 1, −z + 1; (iv) −x + 1, −y + 1, −z.] |
