The title compound, (I) was prepared by a method reported in literature (Walker et al., 2005). The crystals were obtained by dissolving (I) (0.1 g) in methanol (30 ml) and evaporating the solvent slowly at room temperature for about 8 d.
All H atoms were positioned geometrically and constrained to ride on their parent atoms, with C—H = 0.93 Å for aromatic H and 0.96 Å for alkyl H, respectively. The Uiso(H) = xUeq(C), where x = 1.2 for aromatic H and x = 1.5 for other H.

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 > σ(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 title compound is an important intermediate in the synthesis of phenanthrenes, which can be utilized to synthesize organic semiconductors and conjugated polymers (Walker et al., 2005). These materials are of wide current interest for applications in electronic and optoelectronic devices including light-emitting diodes (Kolosov et al., 2002). We report here the crystal structure of the title compound, (I), which is of interest to us in this field.
The molecular structure of (I) is shown in Fig. 1. There is an intermolecular contact C—H···O in the title compound, forming molecular chains along the b axis direction (Table 1, Fig. 2). These molecular chains are linked by weak π—π interactions (Cg1···Cg1i distance = 3.724 (3) Å, Cg1 is the centroid of ring C1-C6, symmetry code: (i) x, 5/2 - y, -1/2 + z) to give a three-dimensional network, which seems to be very effective in the stabilization of the crystal structure.
The dihedral angles between the planes A (atoms C1—C6), B (atoms N/O2/O3), C (atoms C7/C8/H8A/C9/Cl2/Cl3) are: A/B = 16.2 (1)°, A/C = 10.2 (1)°.
