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