, showing the hydrogen-bonded chain structure formed via the O—H⋯N/O⋯·H—N and C—H⋯O hydrogen bonds (dashed lines). H atoms not involved in the hydrogen bonds are omitted for clarity. Symmetry codes: (i) x, −y + $[{2\over 3}]$ , z − $[{1\over 2}]$ ; (ii) x, −y + $[{3\over 2}]$ , −z + $[{1\over 2}]$ .
