In the title compound, C14H13N3O2S, the dihedral angle between the thio­phene and phenyl rings is 24.95 (8)°. The mol­ecular structure is consolidated by intra­molecular N—H⋯O and C—H⋯S inter­actions. The crystal structure features N—H⋯N and N—H⋯O hydrogen bonds forming centrosymmetric R22(12) dimers, which are linked into a two-dimensional network parallel to (011) with an S(6)R22S(6) motif. In addition, π–π stacking inter­actions [centroid–centroid distance = 3.7013 (12) Å] occur between the thio­phene and phenyl rings of adjacent mol­ecules.

Comment top

Multisubstituted thiophenes, particularly their amino derivatives which are widely used as active bio-molecules as inhibitors of several enzymes (Inversen et al., 2000; Webb et al., 2000). Moreover, carbonitril amino thiophen containingg compounds have been used as anticonvulsant and CNS antidepressant agents (El-Sharkawy et al., 2012; Huang et al., 2011). Based on such findings and further to our on going study in the synthesis of potential biologically active compouds, we herein report the synthesis and crystal structure of the title compound.

The bond distances and angles in the title compound (Fig. 1) agree very well with the corresponding bond distances and angles reported in a closely related compound (Mabkhot et al., 2013). In the title molecule, the thiophene and phenyl rings make a dihedral angle of 24.95 (8)° with each other. The molecular structure is consolidated by intramolecular interactions N3—H3NA···O2 and C10—H10···S1 (Tab. 1). The crystal structure is stabilized by N1—H1N···N2 and N3—H3NB···O2 hydrogen bonds (Table 1, Figs. 2 & 3). Furthermore, π-π stacking interactions [Cg1···Cg2 (x, 3/2 - y, -1/2 + z) = 3.7013 (12) Å] between the centroids (Cg1 and Cg2, respectively) of the thiophene and phenyl rings of the consecutive molecules, contribute to the stabilization of the molecular packing of the title compound.

Experimental top

A solution of ethyl chloroacetate (54 ml, 5 mmol) in ethanol (20 ml) was added to a stirred solution of potassium 2,2-dicyano-1-(phenylamino)ethenethiolate (1.19 g, 5 mmol) in distilled water (20 ml) at room temperature. The reaction mixture was heated at 333 – 343 K for about 2 h. The precipitated ethyl 3-amino-4-cyano-5-(phenylamino)thiophene-2-carboxylate was was filtered off, dried and recrystallized from benzene to give high quality crystals (m.p.: 546–548 K) suitable for X-ray analysis in an excellent yield (76%).

Refinement top

The C-bound H atoms were placed geometrically with C—H = 0.95–0.99 Å and were refined using a riding model with Uiso(H) = 1.2 or 1.5Ueq(C). N-bound H atoms were located in a difference Fourier map and were refined freely.

Special details top

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.
