In the title compound, C16H11NO2S2, the dihedral angles between the heterocyclic ring and the phenyl and anilinic benzene rings are 9.68 (13) and 79.26 (6)°, respectively, and an intramolecular C—H⋯S interaction occurs. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds occur, leading to R22(10) loops, and C—H⋯O and weak C—H⋯π interactions further consolidate the packing.

3-Phenyl-2-thioxo-1,3-thiazolidin-4-one (0.419 g, 0.2 mol), 2-Hydroxybenzaldehyde (0.244 g, 0.2 mol) and K2CO3 (0.553 g, 0.4 mol) were dissolved in 10 ml distilled water at room temperature. The stirring was continued for 24 h and reaction was monitored by TLC. The precipitates were formed during neutalization of the reaction mixture with 5% HCl. The precipitates were filtered off and washed with
of NaCl. The crude material obtained was recrystalized in ethyl acetate to affoard orange yellow prisms of (I).The H-atoms were positioned geometrically (O–H = 0.82 Å, C–H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O).
We have recently reported the
of (II) (5Z)-5-(2-Hydroxybenzylidene)-2-thioxo-1,3-thiazolidin-4- one methanol hemisolvate (Shahwar et al., 2009a) and (III) (5E)-5-(4-Hydroxy-3-methoxybenzylidene)-2-thioxo-1,3-thiazolidin- 4-one methanol monosolvate (Shahwar et al., 2009b) which contain the rhodanine. In continuation of synthesizing various derivatives of rhodanine, the title compound (I, Fig. 1), is being reported. The of (IV) 3-Phenyl-5-(phenylmethylidene)-2-thioxo-1,3-thiazolidin-4-one (Linden et al., 1999) has also been published. Title compound (I) differs from (IV) due to attachement of hydroxy group with benzylidene.In (I) the heterocyclic ring A (N1/C7/S1/C8/C9), two benzene rings B (C1—C6) and C (C11–C16) are planar with maximum r. m. s. deviations of 0.0145, 0.0038 and 0.0070 Å respectively, from the respective mean square planes. The dihedral angles between A/B, A/C and B/C are 79.26 (6), 9.68 (13) and 69.62 (6)°, respectively. The intramolecular H-bondings of C—H···S (Table 1, Fig. 1) form twisted S(6) ring motif (Bernstein et al., 1995). The molecules of (I) are stabilized in the form of dimers due to intermolecular H-bondings (Table 1, Fig. 2) froming R22(7) and R22(10) ring motifs. The C–H···π interactions (Table 1) also play role in stabilizing the molecules.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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 recently reported the crystal structure of (II) (5Z)-5-(2-Hydroxybenzylidene)-2-thioxo-1,3-thiazolidin-4- one methanol hemisolvate (Shahwar et al., 2009a) and (III) (5E)-5-(4-Hydroxy-3-methoxybenzylidene)-2-thioxo-1,3-thiazolidin- 4-one methanol monosolvate (Shahwar et al., 2009b) which contain the rhodanine. In continuation of synthesizing various derivatives of rhodanine, the title compound (I, Fig. 1), is being reported. The crystal structure of (IV) 3-Phenyl-5-(phenylmethylidene)-2-thioxo-1,3-thiazolidin-4-one (Linden et al., 1999) has also been published. Title compound (I) differs from (IV) due to attachement of hydroxy group with benzylidene.
In (I) the heterocyclic ring A (N1/C7/S1/C8/C9), two benzene rings B (C1—C6) and C (C11–C16) are planar with maximum r. m. s. deviations of 0.0145, 0.0038 and 0.0070 Å respectively, from the respective mean square planes. The dihedral angles between A/B, A/C and B/C are 79.26 (6), 9.68 (13) and 69.62 (6)°, respectively. The intramolecular H-bondings of C—H···S (Table 1, Fig. 1) form twisted S(6) ring motif (Bernstein et al., 1995). The molecules of (I) are stabilized in the form of dimers due to intermolecular H-bondings (Table 1, Fig. 2) froming R22(7) and R22(10) ring motifs. The C–H···π interactions (Table 1) also play role in stabilizing the molecules.
