(Received 30 January 2009; accepted 2 February 2009; online 6 February 2009)

In the title compound, C14H20N2S2, the 1,3,5-thia­diazinane-2-thione ring adopts an envelope conformation. The S=C bond length is 1.6776 (15) Å, whereas the S—C bond lengths are 1.7470 (15) and 1.8479 (17) Å. The intramolecular C—H⋯S hydrogen bond between the thione and the benzyl units along with the C—H⋯π interaction between the butyl group and the centroid of the benzene ring may be effective in stabilizing the molecule.

Comment top

1,3,5-Thiadiazinane-2-thione nucleus is an important pharmacophoric nucleus and large number of its analogs have been synthesized through different synthetic approaches, including amines and carbon disulfide in aqueous KOH, via diathiocarbamate salt intermediate (Ertan et al., 1991), from isothiocyanates and amines (Ertan et al., 1996), and resin supported solid phase organic synthesis (Aboul-fadi et al., 2002). Diverse bioactivities including antibacterial, antifungal, antimycobactarial, antitubercular, antiprotozoal, leishmanicidal, nematocidal and antiviral are reported for this nucleus in the literature (Coro et al., 2005).

The crystal structure of 5-(2-carboxyethyl)-3-(fur-2-ylmethyl)-tetrahydro- 2H-1,3,5-thiadiazine-2-thione (Perez et al., 2001) contains the same heterocyclic ring as the title compound (I), (Fig 1). The heterocyclic ring is in envelop form with the group (N1/C8/S2/C10/C9) in plane and the N2 displaced by -0.6778 (17) Å from it. The dihedral angle between the benzene ring A(C1—C6) and this group is 81.22 (5)°. The CCDC search (Allen et al., 2002) showed that there are very few crystal structures having 1,3,5-thiadiazinane-2-thione nucleus, so some important bond lengths and bond angles are given in Table 1.

There are no indications of intermolecular contacts, however some weak intramolecular H-bonding is given in Table 2 [CgA is a centroid of the phenyl ring C1–C6].

Experimental top

The 1,3,5-thiadizinane thione was synthesized following the synthetic procedure reported by Ertan et al., 1991. Carbon disulfide (20 mmol) was added portion-wise to a magnetically stirred solution of benzylamine (2.18 ml, 20 mmol) and potassium hydroxide (20 mmol) in 30 ml of water. The contents were stirred for 4 h at room temperature. Formaldehyde (37%, 40 mmol) was added to the reaction mixture and stirred for further 1 h. The reaction content was filtered and the filtrate was added drop-wise to a suspension of n-butylamine (1.97 ml, 20 mmol) to the phosphate buffer (pH 7.8) and stirred for 1 h at ambient temperature. The filterate of the reaction mixture was exhaustively extracted with dichloromethane. The aqueous reaction content was acidified with 15% HCl. The precipitated product was filtered off under suction and thoroughly washed with water. The air dried product was re-crystallized from ethanol. A colourless crystalline product [yield: 76%, m.p.: 381–383 K] was obtained.

Refinement top

H-atoms were positioned geometrically, with C—H = 0.93, 0.96 and 0.97 Å for aromatic, methyl and methylene H, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H, and x = 1.2 for all other H atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
