A packing diagram for (II), viewed down the a axis. Dashed lines indicate N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds. H atoms not involved in hydrogen bonding and the minor component of the disordered water molecule O7′ have been omitted for clarity. Only atoms involved in the hydrogen bonding are labelled. [Symmetry codes: (i) −x + 2, −y + 1, −z + 1; (ii) x − 2, y, z − 1; (iii) x − 1, −y + , z − .] |
