Comment top

Coumarin derivatives exhibit a wide variety of pharmacological activities including anti-HIV (Xie et al., 2001), antibacterial (Tanitame et al., 2004), antioxidant (Shao et al., 1997), antithrombotic (Rendenbach-Müller et al., 1994) and antiinflammatory (Pochet et al., 1996) activities. We have recently reported the crystal structures of some coumarin derivatives (Yang et al., 2007, 2006). As part of our study of the crystal structures of coumarin derivatives, we report here the crystal structure of the title coumarin derivative.

The molecular structure is shown in Fig. 1. The dihedral angle between the coumarin ring system and the phenyl ring is 65.9 (1)°. The terminal SO bond distances of 1.411 (3) and 1.421 (3) Å agree with 1.4207 (19) and 1.4331 (19) Å found in a related compound, 4-methyl-7-phenylsulfonamido-2H-1-benzopyran-2-one (Yang et al., 2007).

In the crystal the molecules are linked by weak C—H···O hydrogen bonding to form the ribbon structure (Table 1 and Fig. 2).

Experimental top

To an anhydrous pyridine solution (10 ml) of 7-hydroxy-4-methyl-coumarin (1.76 g, 10 mmol), a solution of phenylsulfonyl chloride (11 mmol) was slowly added at 278–283 K with stirring for 30 min. The reaction mixture was stirred continuously for 12 h at room temperature and then poured into ice–water (200 ml). The solid obtained was filtered off, washed with water and dried at room temperature. Colorless crystals of the title compound suitable for X-ray structure analysis were obtained by evaporation of an ethanol solution over a period of one week.

Refinement top

H atoms were placed in calculated positions with C—H = 0.93 Å (aromatic) and 0.96 Å (methyl), and refined in riding mode with Uiso(H) = 1.2Ueq(C) (aromatic) and Uiso(H) = 1.5Ueq(C) (methyl).

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.
