Figure 1
The molecular structure of (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines indicate the intramolecular O—H⋯N hydrogen bonds. (a) A projection of (I) on to the mean plane. The molecule is situated on a twofold axis (through atom C14); unlabelled atoms are related to labelled atoms by the symmetry operator (1 − x, y, −z + ). (b) A view of (I) perpendicular to the least-squares plane of the C8–C13 aromatic ring. Note the twist of the molecule at the N atom. |
