In the molecule of the title compound, C
24H
20N
4O
2S, 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).

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).
The S, C and H atoms of the thiophene ring were disordered. During the
refinement process, the disordered atoms were refined with occupancies of
0.654 (3) and 0.346 (3). H atoms were positioned geometrically, with C-H = 0.93
and 0.97 Å for aromatic and methylene H, respectively, and constrained to
ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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. |

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).
