Part of the crystal structure of (II)

, showing the formation of a chain along [001] containing N—H⋯O and C—H⋯O hydrogen bonds only. For the sake of clarity, H atoms bonded to C atoms and not involved in the hydrogen bonding have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (1 − x, 1 − y, − $[{1\over 2}]$ + z) and (1 − x, 1 − y, $[{1\over 2}]$ + z), respectively.
