(Received 3 July 2010; accepted 11 July 2010; online 21 July 2010)

In the title compound, C15H12FN3O3S2, the two six-membered rings are essentially coplanar, their mean plnes making a dihedral angle of 1.1 (2)°. The carbonyl C, the two attached non-fused C atoms and the S atom deviate from the plane of the benzene ring by −0.046 (5), −0.017 (5), 0.000 (6), 0.026 (4) Å, respectively. The angle between the mean planes of the triazole ring and the sulfur heterocycle is 53.3 (1)°. In the crystal, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules in a stacked arrangement along the a axis.

Comment top

The title compound, ethyl 2-((7-fluoro-4-oxo-3-(1H-1,2,4-triazol-1-yl)-4H-thiochromen-2-yl)thio) acetate (I), is a new molecule which has a potential use as antifungal. We herein report its crystal structure.

The molecular structure of (I) is shown in Fig. 1, and selected geometric parameters are given in Table 1. The bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987). The two-ring system is essentially planar [angle between the mean planes = 1.1 (2)°]. The atoms C7, C8, C15 and S2 deviate from the benzene ring by -0.046 (5), -0.017 (5), 0.000 (6), 0.026 (4) Å, respectively. The angle between the mean planes of the triazole ring and the sulfur heterocycle is 53.3 (1)°.

In the crystal packing, a weak intramolecular C4—H4B···S2 interaction is observed, and intermolecular C—H···O hydrogen bonds link the molecules in a stacked arrangement along the a axis.

Experimental top

CS2 (2.0 g, 26.3 mmol) was dropwise added to a solution of 1-(2,4- difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone (5 g, 22.4 mmol) in DMSO (20 ml) containing NaOH (1.8 g, 45 mmol). The yellow solution was stirred for about 2 h at room temperature. Then ethyl bromoacetate (3.8 g, 22.4 mmol) was dropwise added to the intermediate. After 3 h, the solution was poured into water (50 ml). The crystalline product was isolated by filtration, and washed with water (300 ml). The crystals were obtained by dissolving (I) in acetone (20 ml) and evaporating acetone slowly at room temperature for about 7 d.

Refinement top

H atoms were positioned geometrically with C—H = 0.93 Å for aromatic H atoms, C—H = 0.97 Å for methylene H atoms,and with C—H = 0.96 Å for methyl H atoms, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C), where x = 1.2 for aromatic and methylene H atoms and x = 1.5 for methyl H atoms.

Special details top

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.
