A packing diagram for (I), viewed down the a axis. Dashed lines indicate O—H⋯O and N—H⋯O hydrogen bonds. H atoms not involved in hydrogen bonding have been omitted for clarity. Only atoms involved in the hydrogen bonds are labelled. [Symmetry codes: (i) x − , −y + , z − ; (ii) x, y − 1, z; (iii) x, y + 1, z.] |
