Compound (I) was obtained from the Tasly Group, a pharmaceutical company in Tianjin. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a methanol solution at room temperature.
The occupancies of the disordered positions C23/C23' and C24/C24' were refined to 0.646 (13)/0.354 (13). The C—C distances involving the disordered atoms were restrained to 1.52 (1) Å, and the Uij components of these atoms were approximated to isotropic behaviour. The H atoms were placed in calculated positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.98 Å [Uiso(H) values of 1.2 or 1.5 (methyl) times Ueq(C)]. However, a short H21B···H23D contact of 1.73 Å involving a disordered H atom is observed. In the absence of significant anomalous dispersion effects, Friedel pairs were merged before the final refinement.

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, (I), the main active component isolated from the rhizome of Salvia miltiorrhiza Bunge and Salvia przewalskii Maxim (Labiatae), has been used widely in China to treat coronary heart diseases, particularly angina pectoris and myocardial infarction (Xue et al., 1999). We report here the crystal strucure of (I).
The asymmetric unit of (I) contains two crystallographically independent molecules (Fig. 1). The corresponding bond lengths and angles of these two molecules agree with each other (Table 1). The C14—C15 and C33—C34 bond distances agree with the corresponding distance of 1.5628 (19) Å, reported for 8,9-dihydro-1,6-dimethylphenanthro[1,2-b]furan-10,11-dione (Qin et al., 2005). In one of the moleules, the cyclohexene ring A is disordered. In both molecules, ring A adopts a half-chair conformation and the five-membered ring D adopts a distorted half-chair conformation. Intramolecular C—H···O hydrogen bonds are observed in the molecular structure (Table 2), but no intermolecular hydrogen bonding is observed in the crystal structure.
