3,10,14,21-Tetra­kis(4-meth­oxy­phen­yl)penta­cyclo­[11.8.0.0(2,11).0(4,9).0(15,20)]henicosa-1(21),2,4(9),5,7,10,13,15(20),16,18-decaen-12-one chloro­form monosolvate

The asymmetric unit of the title compound, C(49)H(36)O(6)·CHCl(3), 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 CHCl(3). 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.
