The 1,2,4-triazole ring is statistically planar [r.m.s. deviation = 0.002 (2) Å] and the phenyl substituent is almost perpendicular to its mean plane [dihedral angle = 83.57 (11)°]. No directional intermolecular interactions were observed in the crystal structure.

Comment top

In continuation of our interest in the chemical and pharmacological properties of adamantane derivatives (Kadi et al., 2010), we synthesized the title compound (I) as a potential chemotherapeutic agent and herein its crystal structure is reported.

In the molecule of the title adamantyl derivative, C₂₁H₂₇N₃OS, (Fig. 1) the terminal methoxyethyl unit is disordered over two orientations with the refined site-occupancy ratio of 0.845 (6):0.155 (6). The 1,2,4-triazole ring is planar with an r.m.s. deviation of 0.002 (2) Å. The phenyl substituent is almost perpendicular to the mean plane of the 1,2,4-triazole ring with the dihedral angle of 83.57 (11)°. The adamantyl group is planarly attached to the 1,2,4-triazole ring at atom position 5 or atom C2. The 2-(methoxyethyl)sulfanyl substituent is planarly attached to this five-membered ring with the torsion angle C1–S1–C19–C20 = 179.61 (15)°. The orientation of the terminal disordered methoxyethyl unit can be indicated by the torsion angles C21–O1–C20–C19 = -176.1 (2)° for the major component (A) and 127.7 (7)° for the minor component (B). The bond distances in (I) are comparable with those in related structures (Al-Abdullah et al., 2012; Almutairi et al., 2012; El-Emam et al., 2012; Fun et al., 2011 and Wang et al., 2011).

Even though no intermolecular hydrogen bond was observed in the crystal packing of (I), however the crystal packing was shown in Fig. 2 to illustrate the arrangement of the molecules.

Experimental top

A mixture of 3-(adamantan-1-yl)-4-phenyl-4H-1,2,4-triazole-5-thiol (623 mg, 2 mmol), 1-bromo-2-methoxyethane (278 mg, 2 mmol) and anhydrous potassium carbonate (276 mg, 2 mmol) in N,N-dimethylformamide (5 ml) was stirred at room temperature for 24 h. Water (15 ml) was added and the mixture was stirred for 30 min. The separated crude product was filtered, washed with water, dried and crystallized from aqueous ethanol to yield 196 gm (53 %) of the title compound as colorless plate-shaped crystals, M.p. 428-430 K.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
