Figure 1 The molecular structure of (I), showing the atom-labelling scheme and the intermolecular O–H⋯O hydrogen-bonding interactions. Displacement ellipsoids are drawn at the 30% probability level. The atoms labelled with the suffixes A, B, C, D, and E are generated by the symmetry operations (–x, –y, 1 –z), (–x, –y + 1, –z + 1), (–x, y − 1, z), (x, y, z + 1), and (–x, –y, –z), respectively. |
