(Received 2 April 2013; accepted 3 April 2013; online 10 April 2013)

In the title compound, C13H19N3S, the methyl­amine substituent is coplanar with the thia­diazole ring to which it is attached [C—N—C—S torsion angle = 175.9 (2)°] and the amine H atom is syn to the thia­diazole S atom. Supra­molecular chains along [101], sustained by N—H⋯N hydrogen bonding, feature in the crystal packing.

Comment top

Derivatives of adamantane have long been known for their diverse biological activities including anti-viral activity against influenza (Togo et al., 1968) and HIV viruses (El-Emam et al., 2004). Moreover, 1,3,4-thiadiazole derivatives were reported to exhibit marked anti-trypanosomal (Carvalho et al., 2008) and anti-microbial activities (Foroumadi et al., 1999). In continuation of our interest in the chemical and pharmacological properties of adamantane derivatives, and as part of on-going structural studies of these (El-Emam et al., 2012; Almutairi et al., 2012), we report herein the X-ray crystallographic data of the title compound, (I).

In (I), Fig. 1, the five-membered ring is planar (r.m.s. deviation = 0.009 Å) and the methylamine substituent is co-planar: the C13—N3—C2—S1 torsion angle is 175.9 (2)°. The amine-H atom is syn to the thiadiazole-S1 atom. N—H···N hydrogen bonds feature in the crystal packing, leading to supramolecular chains along [1 0 1], Fig. 2 and Table 1. Chains pack with no specific intermolecular interactions between them. Globally, the crystal structure comprises alternating layers of hydrophilic and hydrophobic regions, Fig. 3.

Experimental top

The title compound was prepared by dehydrative cyclization of 1-(1-adamantylcarbonyl)-4-methylthiosemicarbazide using sulfuric acid at room temperature for 24 h as previously described (El-Emam & Lehmann, 1994). Single crystals were obtained by slow evaporation from its CHCl3:EtOH solution at room temperature; M.pt: 441–443 K.

Refinement top

The C-bound H-atoms were placed in calculated positions [C—H = 0.96 to 0.98 Å, Uiso(H) = 1.2 or 1.5Ueq(C)] and were included in the refinement in the riding model approximation. The N-bound H-atom was refined with N—H = 0.88±0.01 Å.

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.
