10,10-Dimethyl­anthrone

Abstract

In the title compound, C16H14O, the asymmetric unit consists of three crystallographically independent mol­ecules. The anthracene units are essentially planar, with maximum deviations of 0.165 (1), 0.153 (1) and 0.045 (1) Å in the three mol­ecules. In the crystal structure, mol­ecules are linked via inter­molecular C—H(...)O hydrogen bonds. Further stabilization is provided by C—H(...)π inter­actions.

Comment

Anthrone is a tricyclic aromatic hydrocarbon which is used for a popular cellulose assay and in the colorometric determination of carbohydrates (Trevelyan, 1952). The crystal structures of anthrone (Srivastava, 1964), 10-bromoanthrone (Destro et al., 1973), 9,10-dimethylanthracene (Iball & Low, 1974), benzylideneanthrone at 193 K (Ghosh et al., 1993), 10-(2-methylbenzylid- ene)anthrone (Zhou et al., 2004), 10-(3,4-dimethoxybenzylidene) anthrone (Zhou et al., 2005) and 10-(4-hydroxy-3-nitrobenzylidene) anthrone (Zhou et al., 2007), have been reported. In view of the importance of the title compound, (I), its crystal structure is reported here.

The asymmetric unit of the title compound, consists of three crystallographically independent 10,10-Dimethylanthrone molecules, (A, B & C), as shown in Fig. 1. The bond lengths and angles of molecules A , B and C agree with each other and are within normal ranges (Allen et al., 1987). The anthracene units are essentially planar with maximum deviations of 0.165 (1)Å for atom C3A (molecule A), 0.153 (1)Å for atom C14B (molecule B) and 0.045 (1)Å for atom C14C (molecule C). The two fused benzene rings, C1–C6 and C8–C13, make dihedral angles with the C1/C6–C8/C13–C14 plane of 5.74 (5)° and 3.85 (5)° in molecule A; 4.40 (6)° and 2.79 (6)° in molecule B; and 1.69 (6)° and 1.63 (6)° in molecule C.

In the crystal structure (Fig. 2), the molecules are linked through intermolecular C10—H10A···O1C, C10C—H10C···O1B, C3C—H3CA···O1A C15B—H15D···O1B and C16A—H16A···O1A hydrogen bonds. The structure is further stabilized by C—H···π interactions (Table 1), involving C1A–C6A (centroid Cg1), C1B–C6B (centroid Cg7), C1C–C6C (centroid Cg13) and C8C–C13C (centroid Cg15).

Experimental

The title compound was obtained as a gift sample from R. L. Fine Chem, Bangalore, India. X-ray quality crystals were obtained by slow evaporation from a methanol solution (m. p.: 349–352 K).

Refinement

All hydrogen atoms were positioned geometrically [C–H = 0.93 or 0.96Å] and were refined using a riding model, with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl groups.

Special details

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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.
