In the title N-Mannich bases, 3-(adamantan-1-yl)-4-(4-fluorophenyl)-1-[(4-phenylpiperazin-1-yl)methyl]-4,5-dihydro-1H-1,2,4-triazole-5-thione (C29H34FN5S) (I), and 3-(adamantan-1-yl)-4-(4-fluorophenyl)-1-{[4-(2-methoxyphenyl)piperazin-1-yl]-methyl}-4,5-dihydro-1H-1,2,4-triazole-5-thione (C30H36FN5OS) (II), fluorophenyl, adamantane and piperazine moieties are linked to a planar triazole ring. There is an additional phenyl ring on the piperazine ring in (I) and a methoxyphenyl ring in (II). In compound (I), the fluorophenyl and phenyl rings are inclined to the triazole ring by 86.55 (13) and 60.52 (12)°, respectively, and the two aryl rings are inclined to one another by 66.37 (13)°. In compound (II), the corresponding dihedral angles are 83.35 (13), 71.38 (15) and 11.97 (16)°, respectively. The of (I) shows pairs of C—H⋯F hydrogen bonds forming inversion dimers, while in the crystal of compound (II), in addition to the C—H⋯F hydrogen bonds that generate chains parallel to the b axis, there are C—H⋯π interactions present that link the chains to form layers parallel to the ab plane.
1. Chemical context
The incorporation of an adamantyl moiety into various bioactive molecules results in compounds with relatively high et al., 2011; Lamoureux & Artavia, 2010). Several adamantane-based drugs have been developed as antiviral (Davies et al., 1964; Togo et al., 1968; Rosenthal et al., 1982; El-Emam et al., 2004; Burstein et al., 1999; Balzarini et al., 2009), anti-Parkinsonian (Schwab et al., 1969) and hypoglycaemic (Villhauer et al., 2003; Augeri et al., 2005) drugs. In addition, numerous adamantane-based analogues have promising anticancer (Sun et al., 2002), bactericidal (Protopopova et al., 2005; El-Emam et al., 2013; Kadi et al., 2010; Al-Abdullah et al.; 2014; Al-Deeb et al., 2006) and fungicidal (Omar et al., 2010) activities. In a continuation of our ongoing studies on the pharmacological and structural properties of adamantyl 1,2,4-triazole derivatives (Al-Abdullah et al., 2012; Al-Tamimi et al., 2014; El-Emam et al.; 2013; 2014), we report herein on the synthesis and crystal structures of the title adamantyl-substituted 1,2,4-triazole-5-thione N-Mannich bases, (I) and (II).
which in turn modifies the bioavailability and modulates the therapeutic indices through various mechanisms (Liu2. Structural commentary
The molecular structures of the title compounds, (I) and (II), are illustrated in Figs. 1 and 2, respectively. In both molecules the piperazine rings have a chair conformation, with the N-bound substituents occupying equatorial positions. In (I), the fluorophenyl ring (C13–C18) and the phenyl ring (C24–C29) are inclined to the triazole ring (N1–N3/C11/C12) by 86.55 (13) and 60.52 (12)°, respectively. The two aryl rings are inclined to one another by 66.37 (13)°. In compound (II), the fluorophenyl ring (C13–C18) and the phenyl ring (C24–C29) are inclined to the triazole ring (N1–N3/C11/C12) by 83.35 (13) and 71.38 (15)°, respectively, while the two aryl rings are inclined to one another by only 11.97 (16)°. This difference in conformation is illustrated by the structural overlap diagram, shown in Fig. 3.
3. Supramolecular features
In the crystal of compound (I), molecules are linked by pairs of C—H⋯F hydrogen bonds, forming inversion dimers (Table 1 and Fig. 4). In compound (II), molecules are linked by C—H⋯F hydrogen bonds, forming chains parallel to the b-axis direction. The chains are linked by C—H⋯π interactions, forming layers parallel to the ab plane (Table 2 and Fig. 5).
4. Database survey
A search of the Cambridge Structural Database (Version 5.38, last update May 2017; Groom et al., 2016) for the 3-(adamantan-1-yl)-4-[(piperazin-1-yl) methyl]-1,2,4-triazole-3(3H)-thione moiety gave 14 hits. One compound, 3-(adamantan-1-yl)-4-phenyl-1-[(4-phenylpiperazin-1-yl)methyl]-1H-1,2,4-triazole-5(4H)-thione (GAPWUR; Al-Abdullah et al., 2012), is very similar to compound (I). It has a phenyl ring substituent on the piperazine ring and a phenyl ring substituent on the triazole ring, which are inclined to one another by 72.4 (2)°, and by 89.0 (2) and 74.4 (2)°, respectively, to the triazole ring. In compound (I), the corresponding dihedral angles are 66.37 (13), 86.55 (13) and 60.52 (12)°, respectively. Two compounds have a 2-methoxyphenyl ring substituent on the piperazine ring, viz. (3-(1-adamantyl)-1-{[4-(2-methoxyphenyl)piperazin-1-yl]methyl}-4-methyl-1H-1,2,4-triazole-5(4H)-thione (YUPVIP; El-Emam et al., 2014), with a methyl substituent on the triazole ring, and 3-(adamantan-1-yl)-4-ethyl-1-{[4-(2-methoxyphenyl)piperazin-1-yl]methyl}-1H-1, 2,4-triazole-5(4H)-thione (RITMUE; Al-Tamimi et al., 2010) with an ethyl substituent on the triazole ring. In these two compounds the methoxyphenyl rings are inclined to the triazole ring by 67.1 (1) and 59.4 (1)°, respectively. In compound (II), the corresponding dihedral angle is 71.38 (15)°.
5. Synthesis and crystallization
The title compounds, (I) and (II), were synthesized via the reaction of 3-(adamantan-1-yl)-4-(4-fluoromethyl)-4H-1,2,4-triazole-5-thiol (Al-Deeb et al., 2006) with the appropriate monosubstituted piperazie and a formaldehyde solution, as outlined in Fig. 6.
Compound (I): 1-Phenylpiperazine (325 mg, 2 mmol) and a 37% formaldehyde solution (1 ml) were added to a solution of 3-(adamantan-1-yl)-4-(4-fluoromethyl)-4H-1,2,4-triazole-5-thiol (659 mg, 2 mmol) in ethanol (10 ml), and the mixture was heated under reflux for 1 h then allowed to stand overnight. Cold water (3 ml) was slowly added and the mixture was stirred for 20 min. The precipitated crude product was filtered, washed with water, dried, and crystallized from ethanol to yield 846 mg (84%) of compound (I) as colourless plate-shaped crystals (m.p. 469–471 K). 1H NMR (700.17 MHz): δ 1.47–1.49 (m, 3H, adamantane-H), 1.60–1.62 (m, 3H, adamantane-H), 1.80 (s, 6H, adamantane-H), 1.89 (s, 3H, adamantane-H), 2.89–2.91 (m, 4H, piperazine-H), 3.14–3.15 (m, 4H, piperazine-H), 5.14 (s, 2H, CH2), 6.77–6.79 (m, 1H, Ar-H), 6.94 (d, 2H, Ar-H, J = 8.4 Hz), 7.20–7.22 (m, 2H, Ar-H), 7.41–7.49 (m, 4H, Ar-H). 13C NMR (125.76 MHz): δ 27.61, 36.07, 39.62, 39.74 (adamantane-C), 48.73, 50.30 (piperazine-C), 69.06 (CH2), 116.0, 116.78, 119.41, 129.37, 132.80, 133.10, 151.48, 156.28 (Ar-C), 162.17 (triazole C-3), 170.95 (C=S).

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. |

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. |
