A view of the packing structure of (I), showing the hydrogen-bonding interactions (dashed lines). The hydrogen-bonded rings A and B are defined in the Comment. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (i) 2 − x, 1 − y, 1 − z; (ii) 1 − x, 1 − y, −z.] |
