The asymmetric unit of the title compound, C14H18N2S, contains two independent and conformationally similar mol­ecules, which form cyclic dimers via inter­molecular hydrogen bonds of the type N—H⋯S [graph set R22(8)]. The structure is iso­morphous with that of one of the polymorphs of 4,4,6-tri­methyl-1-phenyl-3,4-dihydro­pyrimidine-2(1H)-thione [Yam­in et al. (2005[Yamin, B. M., Kasim, N. A. M. & Hamzah, N. (2005). Acta Cryst. E61, o55-o57.]). Acta Cryst. E61, o55–o57].

Comment top

The title compound C14H18N2S (I) belongs to a novel and rare class of dihydropyrimidine-2-thiones. Their synthesis has been attracting widespread attention because of their diverse pharmacological properties such as antibacterial (Alam et al., 2005), antitumour (Swamy et al., 2005) and antioxidative activities (Sriram et al., 2006). The crystal structure of a closely related compound, 4,4,6-trimethyl-1-phenyl-3,4-dihydropyrimidine-2(1H)-thione (Yamin et al., 2005) and its triclinic polymorph (Ismail et al., 2007) have been reported.

The asymmetric unit of the title compound is composed of two molecules (Fig. 1) exhibiting intermolecular hydrogen bonds of the type N—H···S (Table 1) forming cyclic dimers [graph set R22(8) (Etter et al., 1990)]. The two molecules are conformationally similar [e.g. the inter-ring torsion angle C1–N2–C8–C13 (molecule 1), -83.1 (3)° and C15–N4–C22–C27, -85.9 (3)° (molecule 2)] and are related by pseudo two-fold rotational symmetry. The title compound is isomorphous with one of the polymorphs of 4,4,6-trimethyl-1-phenyl-3,4-dihydropyrimidine-2(1H)-thione (Yamin et al., 2005). However, in the triclinic polymorph of this related compound (Ismail et al., 2007), which also forms a cyclic dimer, the two molecules have crystallographic inversion symmetry.

Experimental top

The title compound was prepared by the reaction of 3-methylaniline with 4-methylpent-3-en-2-one in the presence of potassium thiocyanate in acetone: details of the synthesis will be reported later. Recrystallization from methanol afforded the title compound as colourless crystals: Anal. calcd. for C14H18N2S: C, 68.25; H, 7.36; N, 11.37; S, 13.01%; found: C, 68.09; H, 7.41; N, 11.51; S, 13.12.

Refinement top

All H-atoms were visible in the difference Fourier maps but were included in the refinements at geometrically idealized positions with distances: N—H = 0.88 Å and C—H = 0.95 and 0.98 Å, with Uiso = 1.2Ueq of the atoms to which they were bonded. The final difference map was free of chemically significant features.

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 > 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.
