In the title compound, C16H10O6, the complete mol­ecule is generated by a crystallographic centre of symmetry. In the crystal, O—H⋯O hydrogen bonds link the mol­ecules into (100) sheets and C—H⋯O links also occur.

Comment top

Substituted phthalides (isobenzofuran-1(3H)-ones) represent an important class of natural products that posses significant biological properties (e.g. Pedrosa et al., 2006). As part of our search for new biologically active compounds, we unexpected obtained the title compound, (I), which is a typical derivative of phthalides.

In the crystal structure of compound (I) (Fig. 1),there is an inversion center, which is located at the mid-point of C(8)—C(8 A) bond. All of the bond lengths and bond angles are in the normal ranges (Wang et al., 2001). In the crystal lattice, there are a C—H···O intramolecular hydrogen bond and an O—H···O intermolecular hydrogen bond, which stabilize the molecule structure.

Experimental top

Phthalic anhydride (0.05 mol) was dissolved in dichloromethane (100 ml). Then, AlCl3 (0.05 mol) was added. The mixture was stirred at room temperature and the whole reaction was under the protection of nitrogen. After 5 h, the reaction was stopped and the mixture poured into ice-water. The organic layer was collected and then was dried with MgSO4. Finally, the organic layer was concentrated by rotary vacuum evaporation to obtain yellow solids. Yellow blocks of (I) were obtailed by recrystallization from acetonitrile at room temperature.

Refinement top

The H atoms were located in difference maps and freely refined.

Special details top

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.
