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, C₄₉H₃₆O₆·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.

The title compound, C₂₈H₁₈O₂S, is composed of a naphthalene ring system fused with a benzo­thio­phene ring and attached to two phenyl rings. The phenyl rings make dihedral angles of 70.92 (8) and 79.23 (8)° with the essentially planar naphthalene ring system (r.m.s. deviation = 0.031 Å). There is an intra­molecular C—H...π inter­action present. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds which generate C(7) zigzag chains running parallel to [10-1]. The chains are linked via further C—H...π inter­actions, forming a three-dimensional structure.
