The title compound, C13H10ClN3OS, was prepared by the reaction of 3-amino-2-chloropyridine with benzoyl isothiocyanate at room temperature. The thiourea group makes dihedral angles of 47.17 (5) and 51.88 (4)°, respectively, with the benzene and pyridyl rings, while the angle between the benzene and pyridine rings is 8.91 (3)°. Intermolecular hydrogen-bond interactions link neighbouring molecules into an infinite supramolecular structure.

N-Benzoyl-N'-(2-chloro-3-pyridyl)thiourea was synthesized according to an analogous method reported earlier (Ding et al., 2008). Benzoyl chloride (702.8 mg, 5.00 mmol) was reacted with ammonium thiocyanate (380.6 mg, 5.00 mmol) in acetonitrile solution (25 ml) continuring stirring for 3 h at room temperature, to give the corresponding benzoyl isothiocyanate, which was added 3-amino-2-chloropyrldine (642.8 mg, 5.00 mmol). After stirring for 20 h at room temperature, the precipitate was reduced pressure filtered, washed successively with acetonitrile and diethyl ether. The product was dried in vacuo, and obtained 599.2 mg of needle-like crystalline solid. Yield, 41.07%. m.p. 424–426 K. Colorless single crystals suitable for X-ray diffraction studies were obtained after two weeks by slow evaporation from a mixture of ethyl acetate/acetone (1:1) of N-benzoyl-N'-(2-chloro-3-pyridyl)thiourea at room temperture. Analysis calculated for C13H10ClN3OS (%): C 53.52, H 3.45, N 14.40. Found: C 53.61, H 3.51, N 14.3.

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. |

Benzanilide and its N-substituted derivatives have been considered to be a class of privileged structural compounds, which usually have excellent biological activities (Teoh et al., 1999; Campo et al., 2002). However, the literatures are full of the function of the 2-chloro-4-nitrophenyl (Saeed et al., 2008), 3,5-dichlorophenyl (Gowda et al., 2008a) and 3-chlorophenyl (Gowda et al., 2008b; Gowda et al., 2008c) and also structures of benzamide and related compounds. As an extension of our work (Dong et al., 2006; Dong et al., 2007; Dong et al., 2008a; Dong et al., 2008b) on synthesis and structural characterization of thiourea and its derivatives, here report the synthesis and structure of the title compound.
In the molecule of the title compound, N-benzoyl-N'-(2-chloro-3-pyridyl)thiourea (Fig. 1), which is isomeric compound to its observed in the structures of N-(2-chlorobenzoyl)-N'-(3-pyridyl)thiourea (Chai et al., 2008). The thiourea group makes dihedral angles of 47.17 (5)° and 51.88 (4)° with the benzene and pyridyl rings respectively, while the angle between the benzene and pyridine rings is 8.91 (3)°. The carbonyl group forms an intramolecular hydrogen bond with the N2—H2 group, which forms a six-membered ring (C2/N1/C1/N2/H2/O1) structure, the H2···O1 bond length is 1.94 Å. The C═O bond length with 1.218 (3) Å is longer than the average C═O bond length [1.200 Å], which is due to intramolecular hydrogen bonding. This is similar to the situation found in the structure of N-benzoyl-N'-(3-pyridyl)thiourea (Dong et al., 2006). The crystal structure is further stabilized by intermolecular N1—H1···S1 and C12—H12···O1 hydrogen bonds interactions (Table 1, Fig. 2), which link neighbouring molecules into an infinite supramolecular structure.
