Fluorenonophane chloro­benzene solvate: mol­ecular and crystal structures

The title compound, 19H,79H-3,5,9,11-tetra­oxa-1,7(2,7)-difluorena-4,10(1,3)-dibenzena­cyclo­dodeca­phane-19,79-dione (fluorenonophane), exists as a solvate with chloro­benzene, C42H28O6·C6H5Cl. The fluorenonophane contains two fluorenone fragments linked by two m-substituted benzene fragments. Some decrease in its macrocyclic cavity leads to a stacking inter­action between the tricyclic fluorenone fragments. In the crystal, the fluorenonophane and chloro­benzene mol­ecules are linked by weak C—H⋯π(ring) inter­actions and C—H⋯Cl hydrogen bonds. The Cl atom of chloro­benzene does not form a halogen bond. A Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter­molecular contacts found in the crystal structure.
