✦ Synopsis

In the title compound, C~22~H~15~NO~5~, prepared from anthrone and 4-hydroxy-3-methoxy-5-nitrobenzaldehyde, the anthracene fragment is non-planar. The central six-membered ring assumes an asymmetric boat conformation, while the two outer benzene rings make a dihedral angle of 28.08 (10)°. The hydroxy group is involved in an intramolecular hydrogen bond. In the crystal structure, a weak intermolecular C—H...O hydrogen bond links the molecules into ribbons along the c axis.

The title compound, C 17 H 12 O 6 , forms an infinite onedimensional zigzag-like chain developing parallel to the b axis through O-HÁ Á ÁO hydrogen bonds. The chains are stacked along the c axis. The crystal structure is further stabilized by weakand C-HÁ Á Á interactions.
