(Received 19 November 2012; accepted 28 November 2012; online 5 December 2012)

The title compound, C15H13ClN2O2S, exists in the solid state in its thione form with typical thio­urea C—S and C—O bonds lengths as well as shortened C—N bonds. An intra­molecular N—H⋯O hydrogen bond stabilizes the mol­ecular conformation. In the crystal, N—H⋯S hydrogen bonds link the mol­ecules into centrosymmetric dimers.

Comment top

The background to this study has been set out in our previous work on the structural and coordination chemistry of N,N'-disubstituted thioureas (Rauf et al., 2012). Herein, as a continuation of these studies, the structure of the title compound (I) is described. A depiction of the molecule is given in Fig. 1. Bond lengths and angles are comparable to those for other N,N'-disubstituted thioureas reported in the Cambridge Structural Database (Allen, 2002). The molecule exists in the thione form with typical thiourea C—S and C—O bonds as well as shortened C—N bond lengths. The molecule features an intramolecular N—H···O hydrogen bond and in the solid molecules associate via intermolecular N—H···S hydrogen bonds which link the molecules into centrosymmetric dimers (Table 1 and Fig. 2).

Experimental top

Freshly prepared 2-chlorobenzoyl isothiocyanate (1.98 g, 10 mmol) was stirred in acetone (50 mL) for 30 minutes. Distilled 3-methoxyaniline (1.23 g, 10 mmol)was then added and the resulting mixture was stirred for 1 h. The reaction mixture was then poured into acidified (pH 4) water and stirred. The solid product was separated and washed with deionized water and purified by recrystallization from methanol/dichloromethane (1:10 v/v) to give fine crystals of (I) with an overall yield of 93% (2.98 g).

Refinement top

Hydrogen atoms were included in calculated positions and refined as riding on their parent atom with N—H = 0.88 Å and Uiso(H) = 1.2U(Neq), Caromatic—H = 0.95 Å and Uiso(H) = 1.2U(Ceq) or C—H = 0.98 Å and Uiso(H) = 1.5U(Ceq), for methyl C atoms.

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.
