Figure 2
A packing diagram for (I), showing (a) ribbons of (I) along the a axis and (b) the inter-ribbon hydrogen-bond network resulting in the column motif along the a axis. (In the electronic version of the journal, hydrogen bonds between molecules forming the heteromolecular dimer are indicated by blue dashed lines, and red and green dashed lines, respectively, represent hydrogen bonds involved in forming the ribbon and column motifs.) Some H atoms and intramolecular hydrogen bonds have been omitted for clarity. [Symmetry codes: (i) −x + 2, −y + 2, −z + 1; (ii) x + 1, y, z; (iv) x − 1, y, z.] |
