In the title compound, C14H13NOS2, the S atom with the methyl group is involved in an intra­molecular hydrogen bond with the amido H atom. In the crystal, the sulfanyl H atoms form inter­molecular hydrogen bonds with the O atoms, connecting the mol­ecules into zigzag chains along the c axis. The two aromatic rings exhibit a small interplanar angle of 16.03 (9)°.

The N—H···S hydrogen bonding interactions are quite often found in proteins, where the sulfur atoms are ususally from cysteine or methionine residues. Many organic compounds containing amide and thiol (or thioether) moieties were investigated to give a deep insight of the N—H···S hydrogen bonding interactions (Du et al. 2009), which may help to understand protein folding processes and enzymatic catalyses. Our group is interesting in the preparation and encapsulation behaviors of organic and inorganic supramolecules with dynamic covalent bonds (Huang et al. 2012; Wu et al. 2012). The title compound is a sulfur-containing secondary amide with two aryl groups. We synthesized and report its structure here, and will atempt to use it as a building block for the construction of more complex organic or inorganic molecules with unique properties.

The title compound crystallizes in the monoclinic space group P 21/c. Fig. 1. shows a displacement ellipsoid plot of the compound. The S—C(sp3) bond distane of 1.7876 (19) Å is slightly longer than those of the S—C(sp2) bonds [1.7678 (17) and 1.7708 (17) Å]. The two aromatic rings (C2 to C7) and (C9 to C14) exhibit a small interplanar angle of 16.03 (9) °. Both classical and non-classical hydrogen bonds are present (Table 1). The S atom with the Me group involves in an intramolecular hydrogen bond with the amido H-atom [N···S = 2.9150 (14) Å]. A non-classical intramolecular hydrogen bond of the type C—H···O also exists [C···O = 2.949 (2) Å]. In the crystal structure, the H atoms upon S atoms form intermolecular hydrogen bonds with the O atoms [S···O = 3.5976 (14) Å], connecting the compounds into zigzag chains along the c axis (Fig. 2).

Experimental top

A CH2Cl2 solution (20 ml) containing 2-methylthioaniline (1.39 g, 10 mmol) and NEt3 (1.02 g, 10 mmol) was mixed with another CH2Cl2 solution (20 ml) containing 2,2'-dithiosalicyl chloride (1.7 g, 5 mmol). After stirred at room temperature for 12 h, the mixture was washed with saturated NaHCO3 solution and distilled water. The combined CH2Cl2 portions were collected and dried with anhydrous MgSO4. The solvent was then removed under vacuum to afford a yellow powder. An uncapped 50 ml flask, containing the yellow solid and an excess NaBH4 (0.33 g, 9 mmol), was placed in an ice-water bath. To this flask, 25 ml of MeOH was added slowly. After the resulting mixture stirred at 4°C for 10 minutes, the water bath was removed and the stirring was continued for another 30 minutes. The yellowish mixture was added dropwise with concentrated HCl(aq) to quench excess NaBH4. After completion, the solution was extracted with CH2Cl2 and distilled water. The collected CH2Cl2 fractions were dried over anhydrous MgSO4, filtered, and vacuum dried to give 2.03 g of light-yellow solid (86% yield). Crystals suitable for X-ray diffraction analysis were obtained by slow evaporation of THF solution of the compound at -4°C.

Refinement top

The H on C atoms were positioned geometrically and refined as riding atoms, with Caryl—H = 0.93 and Cmethyl—H = 0.96 Å while Uiso(H) = 1.2Ueq (Caryl) and 1.5Ueq (Cmethyl). The H on N and S atoms were located from the difference Fourier map and freely refined (N1—H8 = 0.83 (2) Å and S2—H13 = 1.24 (3) 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.
