Abstract

The asymmetric unit of the title compound, C49H 36O6·CHCl3, contains half an organic molecule, the complete molecule being generated by the operation of a crystallographic twofold rotation axis, and half a highly disordered chloroform molecule. The contribution to the diffraction pattern of the latter was removed using the program SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148-155]; the unit-cell characteristics take into account the presence of CHCl3. The dihedral angles between the planes of the naphthalene ring system and the methoxybenzene rings are 71.05(7) (syn to the central C=O group) and 57.27(6)° (anti to the central C=O group). In the crystal, molecules are linked by C - H⋯O interactions, generating C(12) chains running parallel to the b axis.
