In the title compound, C10H7NO2S2·0.5CH3OH, the dihedral angle between the aromatic rings is 11.43 (11)° and a short intramolecular C—H⋯S contact occurs. The methanol solvent molecule is equally disordered over two sets of sites. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds occur. The methanol solvent molecule connects the dimers through O—H⋯S and O—H⋯O intermolecular hydrogen bonds. Further stability is afforded by C—H⋯π and π–π interactions [centroid–centroid separation = 3.5948 (13) Å].

Rhodanine (0.266 g, 0.2 mol), salicylaldehyde (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 methanol to affoard light red needles of (I).The multiplicity factor of C and O atom of methanol was intially refined and later it was fixed to 0.5.
The coordinates of H-atom of hydroxy group were refined. The coordinates of H-atoms of methanol were also refined with constraints. The H-atoms were positioned geometrically with N—H = 0.86, C—H = 0.93 Å for aromatic like H atoms and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C, N, O), where x = 1.5 for methyl H-atoms and x = 1.2 for all othe H atoms.
The title compound (I, Fig. 1) has been prepared owing to medicinal properties of rhodanine derivatives.
The
of (II) (Z)-5-(2-Fluorobenzylidene)-2-thioxothiazolidin-4-one (Delgado et al., 2006) and (III) 5-(2-Hydroxybenzylidene)-2-thioxo-1,3-thiazolidin-4-one dimethylsulfoxide solvate (Barreiro, et al., 2007) have been published. The title compound (I) differs from (III) due to solvate i.e methanol instead of dimethylsulfoxide.The title molecule basically consits of dimers due to intermolecular H-bondings of N—H···O type with R22(8) ring motifs (Bernstein et al., 1995). There exist a strong interamolecular H-bonding of C—H···S type and two weak intramolecular H-bondings of C–H···O (Table 1, Fig. 2) forming a twisted S(6) and two planar S(5) ring motifs. In (I), the 2-Hydroxybenzylidene moiety A (C1—C7/O1) and the rhodanine moiety B (C8/C9/N1/C10/S1/S2/O2) are planar with maximum r.m.s. deviations of 0.0042 and 0.0044 Å, respectively from their mean square planes. The dihedral angle between A/B is 11.35 (10)°. The methanol solvent of crystallization connects the dimers through O—H···S and O—H···O intermolecular H-bondings and form another ring motif R33(10) (Fig. 2). The molecules are stabilized in the form of two dimensional polymeric networks due to C—H···π interaction (Table 1) and π–π interactions between the centroids of heterocyclic ring Cg1 (C8/C9/N1/C10/S1) and the benzene ring Cg2 (C1—C6). The distance between Cg1···Cg2i [symmetry code i = x, 1 + y, z] and Cg2—Cg1ii [symmetry code ii = x, -1 + y, z] is 3.5948 (13) Å.

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. |

The title compound (I, Fig. 1) has been prepared owing to medicinal properties of rhodanine derivatives.
The crystal structure of (II) (Z)-5-(2-Fluorobenzylidene)-2-thioxothiazolidin-4-one (Delgado et al., 2006) and (III) 5-(2-Hydroxybenzylidene)-2-thioxo-1,3-thiazolidin-4-one dimethylsulfoxide solvate (Barreiro, et al., 2007) have been published. The title compound (I) differs from (III) due to solvate i.e methanol instead of dimethylsulfoxide.
The title molecule basically consits of dimers due to intermolecular H-bondings of N—H···O type with R22(8) ring motifs (Bernstein et al., 1995). There exist a strong interamolecular H-bonding of C—H···S type and two weak intramolecular H-bondings of C–H···O (Table 1, Fig. 2) forming a twisted S(6) and two planar S(5) ring motifs. In (I), the 2-Hydroxybenzylidene moiety A (C1—C7/O1) and the rhodanine moiety B (C8/C9/N1/C10/S1/S2/O2) are planar with maximum r.m.s. deviations of 0.0042 and 0.0044 Å, respectively from their mean square planes. The dihedral angle between A/B is 11.35 (10)°. The methanol solvent of crystallization connects the dimers through O—H···S and O—H···O intermolecular H-bondings and form another ring motif R33(10) (Fig. 2). The molecules are stabilized in the form of two dimensional polymeric networks due to C—H···π interaction (Table 1) and π–π interactions between the centroids of heterocyclic ring Cg1 (C8/C9/N1/C10/S1) and the benzene ring Cg2 (C1—C6). The distance between Cg1···Cg2i [symmetry code i = x, 1 + y, z] and Cg2—Cg1ii [symmetry code ii = x, -1 + y, z] is 3.5948 (13) Å.
