Abstract:

The asymmetric unit of the title compound, C34H16O5, contains two independent mol-ecules (A and B) with similar conformations. The two benzene rings attached to the nine-membered ring are inclined to one another at 63.62 (14)° in mol-ecule A and 68.23 (12)° in mol-ecule B. One intra-moleculer C-H⋯O hydrogen bond occurs in mol-ecule A and two are observed in mol-ecule B. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming a three-dimensional network structure with R(2)2(10) and R(2)2(24) ring motifs. Aromatic π-π stacking interactions [centroid-centroid distances = 3.7572 (19), 3.6996 (19) and 3.7043 (19) Å] are also observed. The unit cell contains a pair of voids of 37 (2) Å(3) about an inversion centre but the residual electron density (highest peak = 0.19 e Å(-3) and deepest hole = -0.20 e Å(-3)) in the difference Fourier map suggests that no solvent mol-ecule occupies this void.
