Acta Crystallographica Section E Structure Reports Online, 2010 The asymmetric unit of the title compound, C(17)H(12)O, contains two molecules, in which the fused aromatic ring systems are almost planar [maximum deviations = 0.0529 (9) and 0.0256 (9) Å]. In the crystal, aromatic π-π stacking inter-actions (perpendicular distance of centroids of about 3.4 Å) and strong O-H⋯O hydrogen bonds result in a helical ...
