In the title compound, C19H23N3OS, the oxadiazole and benzene rings are inclined at a dihedral angle of 50.30 (11)°, with the major twist between them occurring at the ring–methylene N—C bond [N—N—C—N torsion angle = −101.2 (2)°]. In the crystal, helical supramolecular chains along [010] are sustained by N—H⋯S hydrogen bonds. These are linked into layers lying parallel to (-101) by methylene–phenyl C—H⋯π interactions.

A mixture of 5-(adamantane-1-yl)-1,3,4-oxadiazole-2-thiol (2.36 g, 0.01 mol), aniline (0.93 g, 0.01 mol) and 37% formaldehyde solution (1.5 ml), in ethanol (15 ml), was stirred at room temperature for 2 h and allowed to stand overnight. The precipitated crude product was filtered, washed with water, dried, and crystallized from ethanol to yield 3.04 g (89%) of the title compound (I) as fine colourless crystals. M.pt: 439–471 K. Colourless prisms were obtained by slow evaporation of its CHCl3-ethanol (1:1; 10 ml) solution held at room temperature. 1H NMR (CDCl3, 500.13 MHz): δ 1.75 (q, 6H, adamantane-H), 2.01 (s, 6H, adamantane-H), 2.12 (s, 3H, adamantane-H), 2.98 (t, 4H, piperazine-H), 3.20 (t, 4H, piperazine-H), 5.06 (s, 2H, CH2), 6.88–6.95 (m, 3H, Ar—H), 7.27 (t, 2H, Ar—H, J = 7.5 Hz). 13C NMR (CDCl3, 125.76 MHz): δ 27.47, 34.40, 36.10, 39.12 (adamantane-C), 49.36, 50.26 (piperazine-C), 69.86 (CH2), 116.43, 120.15, 129.17, 151.22 (Ar—C), 167.91 (C═N), 178.62 (C═S).
The H-atoms were placed in calculated positions [C—H = 0.93 to 0.98 Å, Uiso(H) = 1.2Ueq(C)] and were included in the
in the riding model approximation. The N-bound H-atom was refined with the distance restraint N—H = 0.88±0.01 Å.In continuation of our long-term interest in the chemical and pharmacological properties of adamantane derivatives (El-Emam & Ibrahim, 1991; El-Emam et al., 2004), including structural studies (Al-Tamimi et al., 2013), we describe herein the X-ray
determination of the title compound, (I).In (I), Fig. 1, the oxadiazole ring is strictly planar (r.m.s. deviation = 0.003 Å) and the thione-S1 atom lies in this plane. The benzene ring is highly twisted out of this plane, forming a dihedral angle of 50.30 (11)°; the N2—N1—C13—N3 torsion angle = -101.2 (2)°. Despite the kink in the molecule, the thione-S1 and amine-N3—H atoms are syn, as seen in the S1—C1···N3—H3 torsion angle of 3 (1)°. This allows for the formation of N—H···S hydrogen bonds that lead to helical supramolecular chains along the b axis, Fig. 2 and Table 1. Chains are connected into layers parallel to (101) by methylene-C—H···π(phenyl) interactions, Fig. 3 and Table 1.

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. |

In continuation of our long-term interest in the chemical and pharmacological properties of adamantane derivatives (El-Emam & Ibrahim, 1991; El-Emam et al., 2004), including structural studies (Al-Tamimi et al., 2013), we describe herein the X-ray crystal structure determination of the title compound, (I).
In (I), Fig. 1, the oxadiazole ring is strictly planar (r.m.s. deviation = 0.003 Å) and the thione-S1 atom lies in this plane. The benzene ring is highly twisted out of this plane, forming a dihedral angle of 50.30 (11)°; the N2—N1—C13—N3 torsion angle = -101.2 (2)°. Despite the kink in the molecule, the thione-S1 and amine-N3—H atoms are syn, as seen in the S1—C1···N3—H3 torsion angle of 3 (1)°. This allows for the formation of N—H···S hydrogen bonds that lead to helical supramolecular chains along the b axis, Fig. 2 and Table 1. Chains are connected into layers parallel to (101) by methylene-C—H···π(phenyl) interactions, Fig. 3 and Table 1.
