The molecule of the title compound, C26H24N4O7S, adopts a trans conformation about the central N—N bond, presumably to minimize steric between the substituents on these two atoms. An intramolecular N—H⋯O hydrogen bond occurs. The phenyl ring is disordered over two sets of sites, with an occupancy ratio of 0.624 (8):0.376 (8). The azolidine ring is essentially planar [maximum deviation = 0.008 (5) Å] and makes a dihedral angle of 4.3 (2)° with the benzene ring and dihedral angles of 74.1 (3) and 69.1 (5)°, respectively, with the mean planes of the major and minor components of the disordered phenyl ring. The packing in the crystal is aided by the formation of several weak C—H⋯O and C—H⋯N interactions.

A mixture of 283 mg (1 mmol) (2E)-2-[1-(4-aminophenyl)ethylidene]-N-phenylhydrazinecarbothioamide and 284 mg (2 mmol) dimethyl but-2-ynedioate in 50 ml of ethanol was refluxed and monitored by TLC until completion of the reaction. The excess solvent was evaporated under vacuum and the solid obtained was recrystallized from ethanol to afford clear yellow crystals (M.p. 443–445 K) of X-ray quality.

H atoms attached to carbon were positioned geometrically while that attached to nitrogen was placed in a location derived from a difference map. All were allowed to ride on their parent atoms with N—H = 0.91 Å, C—H = 0.95 and 0.98 Å, with Uiso(H) = 1.5 Uiso(C) for CH3 H atoms and Uiso(H) = 1.2 Uiso(C,N) for the other H atoms. The phenyl ring attached to the N atom of the thiazolidine ring is disordered over two sites in a 0.624 (8):0.376 (8) ratio. The two orientations were refined as rigid groups with AFIX 66 and EADP instructions. The small proportion of reflections observed is a result of the rather poor quality of the very thin crystal specimens.

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 on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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 4-thiazolidinone ring system is a core structure in various synthetic compounds and an important scaffold known to be associated with several biological activities such as hypnotic activity (Chaudhari et al., 1975; Chaudhary et al., 1976), anti-tubercular (Babaoglu et al., 2003), anti-convulsant (Dwivedi et al., 1972; Parmar et al., 1972), anti-bacterial (Bondock et al., 2007; Vicini et al., 2008), anti-cancer (Gududuru et al., 2004; Ottanà et al., 2005), anti-histaminic (Agrawal et al., 2000; Diurno et al., 1999), anti-fungal (Omar et al., 2010), anti-inflammatory (Vigorita et al., 2003), anti-viral (Rawal et al., 2005) properties and cardiovascular effects (Suzuki et al., 1999). Based on such findings and further to our studies on synthesis of a series of thiazolidinones, we report herein the synthesis and crystal structure of the title compound.
The title molecule (I), (Fig. 1), adopts a trans conformation about the central N2—N3 bond, presumably to minimize contact between the substituents on these two atoms. The conformation about the N4—C21 bond is determined by the presence of an intramolecular N4—H1···O6 hydrogen bond (Fig. 1 and Table 1). The azolidine ring (S1/N1/C4–C6) is essentially planar [maximum deviation = 0.008 (5) Å for C5] and makes a dihedral angle of 4.3 (2)° with the benzene ring (C15–C20) and dihedral angles of 74.1 (3) and 69.1 (5)°, respectively, with the mean planes of the major and minor components (C7B–C12B and C7A–C12A) of the disordered phenyl ring.
In the crystal, the molecular packing is stabilized by the several weak C—H···O and C—H···N intermolecular interactions (Fig. 2 and Table 1).
