A suspension of 4,5-diphenyl-4H-1,2,4-triazole-3-thiol (2.0 mmol) and 1,1-dibromomethane (1.0 mmol) in ethanol (10 ml) was stirred at room temperature. The reaction progress was monitored via TLC. The resulting precipitate was filtered off, washed with cold ethanol, dried and purified to give the target product as light yellow solid in 95% yield. Crystals of (I) suitable for single-crystal X-ray analysis were grown by slow evaporation of a solution in chloroform-ethanol (1:1).
All H atoms were positioned geometrically and refined as riding (C—H = 0.95–0.99 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq (C).
Functionalized 1,2,4-triazole derivatives received considerable attention due to their antihypertensive, antifungal and antibacterial properties (Paulvannan et al., 2001; Wahbi et al., 1995). Some crystal structures of 1H-1,2,4-triazole ring containing ether derivatives have been reported recently (Özel Güven et al., 2008a,b). Herewith we report the synthesis and
of the title compound, (I).In (I) (Fig.1), the molecule is situated on a twofold rotational axis, so π-π conjugation, the Csp2-S bond length [S1—C8 = 1.7439 (2) Å] is significantly shorter than the Csp3-S bond length [S1—C15 = 1.8092 (2) Å].
contains a half of the molecule. The 1,2,4-triazole ring is planar with an r.m.s. deviation of 0.023 (2)Å and maximum deviation of 0.0037 (2)Å for atoms C8. The C8 atom shows a distorted Csp2 state with the bond angles of 110.98 (16)° (N2—C8—N3) and 126.50 (14)°(N2—C8—S1). The triazole ring and two attached phenyl rings (C1—C6 and C9—C14) form dihedral angles of 34.3 (2) and 62.2 (2)°, respectively. The dihedral angle between the two phenyl rings is 61.2 (2)°. As a result ofIn the
weak intermolecular C—H···N hydrogen bonds (Table 1) link the molecules into ribbons extended in direction [001].For related structures, see: Özel Güven et al. (2008a,b). For the pharmacological properties of triazole derivatives, see: Paulvannan et al. (2001); Wahbi et al. (1995).

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. |

Functionalized 1,2,4-triazole derivatives received considerable attention due to their antihypertensive, antifungal and antibacterial properties (Paulvannan et al., 2001; Wahbi et al., 1995). Some crystal structures of 1H-1,2,4-triazole ring containing ether derivatives have been reported recently (Özel Güven et al., 2008a,b). Herewith we report the synthesis and crystal structure of the title compound, (I).
In (I) (Fig.1), the molecule is situated on a twofold rotational axis, so asymmetric unit contains a half of the molecule. The 1,2,4-triazole ring is planar with an r.m.s. deviation of 0.023 (2)Å and maximum deviation of 0.0037 (2)Å for atoms C8. The C8 atom shows a distorted Csp2 hybridization state with the bond angles of 110.98 (16)° (N2—C8—N3) and 126.50 (14)°(N2—C8—S1). The triazole ring and two attached phenyl rings (C1—C6 and C9—C14) form dihedral angles of 34.3 (2) and 62.2 (2)°, respectively. The dihedral angle between the two phenyl rings is 61.2 (2)°. As a result of π-π conjugation, the Csp2-S bond length [S1—C8 = 1.7439 (2) Å] is significantly shorter than the Csp3-S bond length [S1—C15 = 1.8092 (2) Å].
In the crystal structure, weak intermolecular C—H···N hydrogen bonds (Table 1) link the molecules into ribbons extended in direction [001].
