2,4-Bis(4-chloro­benzo­yl)-1-(4-chloro­phen­yl)-3,5-di-2-thienylcyclo­hexa­nol methanol hemisolvate

The title compound, C(34)H(25)Cl(3)O(3)S(2)·0.5CH(3)OH, was synthesized by the reaction of thio­phene-2-carbaldehyde with acetophenone and NaOH under solvent-free conditions, using tetra­butylammonium bromide as a phase-transfer catalyst. The central six-membered ring adopts a chair conformation with the bulky thio­phene, 4-chloro­phenyl and 4-chloro­benzoyl substituents in equatorial positions. The hydroxyl group is in an axial position and forms an intra­molecular O—H⋯O hydrogen bond to the carbonyl group of an adjacent 4-chloro­benzoyl substituent. The methanol solvent mol­ecules are disordered equally over two positions within one-dimensional channels, with site occupancy factors of 0.25.
