syn-5,10,15-Tris(dichloro-meth-yl)-5,10,15-trihy-droxy-5H-diindeno-[1,2-a:1',2'-c]fluorene dichloro-methane 0.82-solvate.
The title compound, C(30)H(18)Cl(6)O(3)·0.82CH(2)Cl(2), consists of a slightly cup-shaped seven-ring truxene nucleus with hy-droxy and dichloro-methyl substituents at stereocenters 5R/S, 10R/S and 15R/S. C-Cl distances are in the range 1.759 (4)-1.783 (3) Å. Solvent channels parallel to the b axis appear to be partially occupied by highly disordered dichloro-methane solvent mol-ecules, the contribution of which were removed from the refinement with the SQUEEZE procedure in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. Only one of the OH groups forms a hydrogen bond, which is inter-molecular to another OH group, forming centrosymmetric dimers in the crystal.
