In the title compound, C14H13NO4S, a sulfonamide derivative of phenyl glycine, the aromatic rings are inclined at a dihedral angle of 28.03 (12)°. In the crystal, O—H⋯O hydrogen bonds link the molecules into chains propagating in [100] and a weak C—H⋯O interaction cross-links the chains in the c-axis direction. In the previously published polymorph, the dihedral angle between the aromatic rings is 45.52 (18)° and the structure is stabilized by three different types of ring motif.

Phenyl glycine (2 g, 13.2 mmol) was dissolved in distilled water (15 ml) in a round bottom flask (50 ml). The pH of the solution was maintained at 8–9 using 1M, Na2CO3 solution. Benzene sulfonyl chloride (2.32 g, 13.2 mmol) was then suspended to the solution, and stirred at room temperature until all the suspension had been disappeared. On completion of the reaction the pH was adjusted 1–2, using 1 M HCl with stirring. The precipitate formed was filtered off, washed with distilled water, dried and recrystalized in methanol.
The H atoms for the C atoms were refined geometrically and treated as riding atoms: C—H = 0.93 for aromatic and C—H = 0.98 for the chiral carbon with Uiso(H) = 1.2Ueq. The N—H and O—H were refined in calculated positions and treated as riding atoms: O—H = 0.83 (4) Å, N—H = 0.82 (3) Å, with Uiso(H) = 1.5Ueq(parent O atom) and = 1.2Ueq(parent N atom)

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. |

We have already reported the crystal structures of sulfonamides (Arshad et al., 2008a, b), (Arshad et al., 2009). In continuation of our studies in this area, we report here a new polymorph of our previously published sulfonamide (Arshad et al., 2009a), derivative (II).
The title compound (I) crystallizes in the monoclinic space group P21. The molecule has a chiral center at C13 with a slightly distorted tetrahedral geometry. The dihedral angles between the two aromatic ring are 28.03 (12)° in (I) and 45.52 (18)° in (II). The crystal structure of I has no complex intermolecular interactions like II. There are only two types of hydrogen bonding interaction of O–H—O making a polymeric chain along the a-axes and C–H—O which linked these polymeric chain along c-axes (Fig. 2 and Table 1).
