The title compound, C30H18Cl6O3·0.82CH2Cl2, consists of a slightly cup-shaped seven-ring truxene nucleus with hydroxy and dichloromethyl 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 dichloromethane solvent molecules, the contribution of which were removed from the 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 intermolecular to another OH group, forming centrosymmetric dimers in the crystal.

A solution of lithium dicyclohexylamine was prepared by adding 93 mmol dicyclohexeylamine and 93 mmol n-butyllithium to 75 ml of dried tetrahydrofuran (THF). This solution was added dropwise over one hour to a suspension of 7.3 mmol truxenone in 100 ml of THF and 6 ml of dichloromethane (DCM) at 273 K. The solution was stirred for one hour and then quenched with aqueous ammonium chloride. The THF was removed under reduced pressure and the remaining mixture was extracted with DCM. The resulting organic layer was washed with aqueous citric acid, dried and evaporated. Flash
(silica gel, DCM) was used to isolate 5,10,15-tris(dichloromethyl)-5,10,15-trihydroxy-5H-Diindeno[1,2 - a:1',2'-c] fluorene and further (silica gel, DCM-hexane 3:1) was used to separate the compound into two components. The syn- component reported here crystallized from DCM as yellow blades.Observed structure amplitudes were modified by PLATON to eliminate diffuse electron density found in the solvent accessible channel. All H atoms were placed in calculated positions, guided by difference maps, with C—H bond distances 0.95 (aromatic-H) and 1.00 (alkyl-H) Å, O—H distances 0.84 Å, and displacement parameters Uiso=1.2Ueq (aromatic and alkyl C) and 1.5Ueq (hydroxyl-O), and thereafter refined as riding. A torsional parameter was refined for each OH group.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The nucleus of the title compound is truxene (C27H18, CAS: 548–35-6), a nearly planar seven-ring aromatic molecule. Compounds containing this ring system have been previously investigated for use in liquid crystal devices, chiral recognition systems, and fluorescent probes (Diring & Ziessel, 2009). The title compound was synthesized as an intermediate material in the formation of buckybowls (half-buckminsterfullerenes, Abdourazak et al., 1995). Two isomers were separated by chromatography, and the yellow component is herein shown to be the syn isomer, with all three OH groups on the same side of the truxene nucleus. The molecule has a slightly cupped shape, with three hydroxy groups oriented toward the inside of the cup and three dichloromethyl groups on the outside of the cup. Relative to the mean plane of the central 6-ring (which is a slightly puckered crown, δ(r.m.s.) = 0.01 (1) Å), the three pairs of carbon atoms on the outer rim of the molecule average 0.36 (1) (C4, C5), 0.15 (1) (C13, C14) and 0.07 (1) (C22, C23) Å above the plane. Of the three OH groups available for hydrogen bond formation, only O1 forms a hydrogen bond, to OH group O3 at 2 - x, 1 - y, 1 - z, thus there are centrosymmetric dimers about 1, 1/2, 1/2, as shown in Fig. 2. A solvent channel with a unit cell volume of 330 Å3, parallel to the b axis and centered at 1/2a, displays residual electron density which presumably represents remnants of disordered solvent molecules most of which have evaporated from the crystal since the original synthesis. Procedure SQUEEZE, as implemented in PLATON (Spek, 2009), subtracted 69 electrons from the observed structure amplitudes as an approximate solvent contribution.
