Packing diagram of compound 4 viewed perpendicular to (10) and centred on (1/2, 1/2, 1/2). Two ribbons parallel to the b axis are shown. Thick and thin dashed lines represent inter- and intramolecular hydrogen bonds, respectively. Hydrogen atoms not involved in hydrogen bonding are omitted for clarity. Selected atoms of the asymmetric unit are labelled. |
