(Received 27 March 2009; accepted 3 April 2009; online 8 April 2009)

In the molecule of the title compound, C₂₄H₂₀N₄O₂S, the dihedral angle between the triazole and thiophene rings is 66.80 (4)° and the dihedral angle between the two benzene rings is 63.37 (4)°. An intramolecular C—H⋯O interaction results in the formation of a six-membered ring. A π⋯π contact between the benzene rings, [centroid–centroid distance = 3.918 (2) Å] may stabilize the structure. Weak C—H⋯π interactions are also present. The S, C and H atoms of the thiophene ring are disordered over two positions and were refined with occupancies of 0.654 (3) and 0.346 (3).

The 1,2,4-triazole compounds posses important pharmacological activities such as antifungal and antiviral activities. Examples of such compounds bearing the 1,2,4- triazole residues are fluconazole, the powerful azole antifungal agent as well as the potent antiviral N- nucleoside ribavirin (Tsukuda et al., 1998; Ünver et al., 2008). The 1,2,4-triazole nucleus is associated with diverse pharmacological activities such as antibacterial, hypoglycemic, antihypertensive, analgesic and specific magnetic properties (Colanceska-Ragenovic et al., 2001; Zhu et al., 2000). It was reported that compounds having triazole moieties such as Vorozole, Anastrozole and Letrozole appear to be very effective aromatase inhibitors very useful for preventing breast cancer (Goss & Strasser-Weippl, 2004; Santen, 2003). There are antimicrobial agents having different structures are frequently used in treatment of microbial infections. However, there is an increasing resistance to these drugs. Moreover, some of azole derivatives used as common antibiotics, such as Amphotericin B posses a toxic effect on humans as well as their antimicrobial effects (Clemons et al., 2004). We report herein the crystal structure of the title compound.

In the molecule of the title compound (Fig 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. In the triazole ring, N2-C3 [1.292 (3) Å] bond is shorter than N4-C3 [1.373 (3) Å] bond and they are in agreement with the corresponding values in similar structures containing triazole ring, such as [1.290 (3) and 1.384 Å; Yılmaz et al., 2006] and [1.278 (3) and 1.379 (3) Å;Çoruh et al., 2003]. S1-C32 [1.698 (3) Å] and S1-C35 [1.735 (6) Å] bonds also agree with the corresponding values [1.706 (2) and 1.723 (2) Å;Ünver et al., 2006] and [1.676 (4) and 1.689 (3) Å (Vrábel et al., 2005]. Rings A (N1/N2/N4/C3/C5), B (C13-C18), C (S1/C32-C35) and D (C45-C50), are, of course, planar and they are oriented at dihedral angles of A/B = 63.76 (3), A/C = 66.80 (4), A/D = 4.81 (3), B/C = 68.37 (3), B/D = 63.37 (4) and C/D = 63.57 (3) °. Intramolecular C-H···O interaction results in the formation of a six-membered ring having envelope conformation, with atom O1 displaced by 0.300 (3) Å from the plane of the other ring atoms.

In the crystal structure, the π···π contact between the benzene rings, Cg2—Cg2ⁱ [symmetry code: (i) -x, -y, -1 - z, where Cg2 is centroid of the ring B (C13-C18)] may stabilize the structure, with centroid-centroid distance of 3.918 (2) Å. There also exist weak C—H···π interactions (Table 1).

Experimental top

For the preparation of the title compound, 4-[(3-phenyl-allidenamino)-5-thiophen -2-yl-methyl-2,4-dihydro-1,2,4]triazol-3-one (0.01 mol) was refluxed with an equivalent amount of natrium in absolute ethanol (100 ml) for 1 h. Then, ethyl bromoacetophenon (0.01 mol) was added and refluxed for an additional 5 h. The precipitate was filtered off, washed with water and recrystallized from ethanol/water (1:2) (yield; 70.79%, m.p. 433-434 K).

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.
