, showing the concerted action of the N—H⋯N and C—H⋯N hydrogen bonds. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (1 + x, $[{1\over 2}]$ − y, $[{1\over 2}]$ + z) and (−1 + x, $[{1\over 2}]$ − y, − $[{1\over 2}]$ + z), respectively.
