Figure 1
The molecular structure of half of the title compound with displacement ellipsoids drawn at the 50% probability level. The strong O—H⋯N and weak C—H⋯O/N/C/Cl hydrogen bonds are shown with the nearest neighbours. Symmetry codes: (i) −1 + x, − y, − z; (ii) − + x, − y, + z; (iii) − + x, − y, − + z; (iv) 2 − x, 1 − y, −z. |
