N-[(4-Amino-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-3-yl)meth­yl]-4-methyl­benzamide

Abstract

In the title compound, C11H13N5OS, the dihedral angle between the triazole ring and the benzene ring is 84.21 (7)°. The amino group adopts a pyramidal configuration. An intra­molecular N—H(...)O hydrogen bond stabilizes the mol­ecular structure and generates an S(8) ring. In the crystal, mol­ecules are linked by inter­molecular N—H(...)O, N—H(...)S, N—H(...)N and C—H(...)S hydrogen bonds into layers lying parallel to the bc plane. The crystal structure is further stabilized by aromatic π–π stacking inter­actions [centroid–centroid distance = 3.3330 (7) Å].

Comment

The synthesis of 1,2,4-triazole derivatives has been attracting widespread attention due to their diverse biological activities such as antimicrobial, anti-inflammatory, and analgesic antitumorial activities (Demirbas et al., 2004; Tozkoparan et al., 2000; Turan-Zitouni et al., 1999; Demirbas et al., 2002; Kritsanida et al., 2002; Holla et al., 2002; Foroumadi et al., 2003; Isloor et al., 2009). There are some antimicrobial drugs containing a triazole moiety. For instance, fluconazole and itraconazole are used in medical therapy (Shujuan et al., 2004; Verreck et al., 2003). In addition, Vorozole, Letrozole, Fadrozole, and Anastrozole are nonsteroidal drugs used for the treatment of estrogen-dependent breast cancer (Clemons et al., 2004). Prompted by the diverse activities of 1,2,4-triazole derivatives, we have synthesized the title compound to study its crystal structure.

The geometric parameters of the title compound (Fig. 1) are comparable to its related structures (Fun et al., 2009a, b).The dihedral angle between the triazole ring [C9/N2/N3/C10/N4] and the benzene ring [C1–C6] is 84.21 (7)°. The amino group adopts a pyramidal configuration. An intramolecular N5—H1N5···O1 hydrogen bond stabilizes the molecular structure. In the crystal structure, the molecules are linked by intermolecular N1—H1N1···O1, N3—H1N3···S1, N3—H1N3···N5, N5—H2N5···S1 and C8—H8A···S1 hydrogen bonds (Table 1) into two-dimensional planes parallel to bc plane (Fig. 2). Cg1···Cg1 of 3.3330 (7) Å (-x, 2 - y, 1 - z) interactions further stabilize the crystal structure. Cg1 is centroid of the triazole ring.

Experimental

A mixture of {[(4-methylphenyl)carbonyl]amino}acetic acid (1.93 g, 0.01 mol) and thiocarbohydrazide (1.0 g, 0.01 mol) was taken in a round bottomed flask fitted with a reflux condenser. The mixture was then fused on oil bath for 1 h. The reaction mass was slowly cooled to room temperature and the solid mass was treated with NaHCO3 solution. The separated solid was collected by filtration and dried. Recrystallization was done from a mixture of ethanol-dioxane to yield colourless blocks of (I). Yield: 2.0 g, 76.0%, m.p. = 493–494 K.

Refinement

N-bound hydrogen atoms were located from the difference Fourier map and refined freely. The rest of the hydrogen atoms were positioned geometrically and refined using a riding model. A rotating group model was used for the methyl group.

Special details

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.
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.
