Figure 2 Packing diagram of the title compound viewed aloing the a axis. Dashed lines represent O—H⋯O hydrogen bonds and weak O—H⋯O intermolecular interactions. H atoms not involved in hydrogen bonding are omitted for clarity. [symmetry codes: (i) 1 − x, − y, 2 − z; (ii) x − , 0.5 − y, z − 0.5; (iii) x + , 0.5 − y, 0.5 + z]. |
