In the title compound, C15H15N3OS, there is an intramolecular N—H⋯O hydrogen bond and an intramolecular C—H⋯S hydrogen bond involving the C=O and C=S bonds which lie on opposite sides of the molecule. The molecule is non-planar with the benzene and pyridine rings being inclined to one another by 26.86 (9)°. In the crystal, molecules are linked by pairs of N—H⋯S hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The dimers are linked via C—H⋯S hydrogen bonds, forming slabs parallel to the bc plane.

The title compound shows the bond lengths and angles which are generally normal in N-alkyl-N'-benzoylthiourea compounds. The bond length of the carbonyl [C8—O1 = 1.229 (15) Å] group of the compound have typical double-bond character, as shown in two closely related compounds, viz. 4-methyl-N-[(4-methylpyridin-2-yl)carbamothioyl]benzamide (Adam et al., 2015) and 4-methyl-N-[2-(pyridin-2-yl)ethylcarbamothioyl]benzamide (Adam et al., 2014). However, the thiocarbonylgroup [C9—S1 = 1.6755 (13) Å] is longer than the typical C═S of 1.660 (2) Å. The C—N bond lengths are all shorter than the average single C—N bond length of 1.472 (5) Å, being C8—N1 = 1.3930 (16) Å, C9—N1 = 1.3915 (16) Å, C10—N3 = 1.3411 (16) Å and C10—N2 = 1.4157 (16) Å, thus showing varying degrees of single-bond character. There are two intramolecular hydrogen bonds, viz. C11—H11–S1 and N2—H2–O1, which have lengths of 3.2051 (13) and 2.6372 (14) Å, respectively (Table 1). The bond character of the structure is presumed to be the result of the intramolecular hydrogen bonding that `locks' the molecule into a pseudo-planar six-membered ring structure, similar to structure of the 4-methyl derivative mentioned above (Adam et al., 2015). These results are in agreement with the expected delocalisation in the compound and confirmed by bond angles C9—N2—C10 = 132.02 (11)° and C9—N1—C8 = 128.54 (10)°, indicating sp2 of atoms N1 and N2.
In the crystal, molecules are linked by a pair of N—H···S hydrogen bonds forming inversion dimers with an R22(8) ring motif (Table 1 and Fig. 2). This situation is similar to that in the 4-methyl derivative mentioned above (Adam et al., 2015). The dimers are linked via C—H···S hydrogen bonds forming slabs parallel to the bc plane.
o-Benzoyl chloride (13 mmol) was added dropwise to a stirred acetone solution (30 ml) of ammonium thiocyanate (13 mmol). The mixture was stirred for 10 min. A solution of 2-amino-4-picoline in acetone was added and the reaction mixture was refluxed for 3 h, after which the solution was poured into a beaker containing some ice cubes. The resulting precipitate was collected by titration, washed several times with a cold ethanol/water mixture and purified by recrystallization from an ethanol solution (m.p. 437.9–438.8 K). FT–IR (KBr, cm-1) analysis shows the following vibrational frequencies for N—H, C═O, C—N and C═S at 3237, 1683, 1329 and 1157, respectively. 1H NMR results show chemical shifts at 9.545 and 13.501 p.p.m. for the two N—H protons.
Crystal data, data collection and structure
details are summarized in Table 2. The N—H H atoms were located in a difference Fourier map and freely refined. The C-bound H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.96 Å and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for other H atoms.The title compound shows the bond lengths and angles which are generally normal in N-alkyl-N'-benzoylthiourea compounds.

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. |
