In the structure of the title compound, C12H15N3O3S, the thio­amide and amide groups are almost coplanar with the benzene ring. The planes of the NO2 group and the benzene ring form a dihedral angle of 40.8 (2)°. The crystal packing shows inter­molecular N—H...S hydrogen bonds, forming centrosymmetric dimers which are stacked along [001].

Comment top

The coplanarity of thioamide and amide groups with the phenyl ring are reflected by the torsion angles C6–N1–C1–O1 of -6.1 (2)° and C8–N2–C6–N2 of 1.4 (2)°. This is a common feature for this type of compounds (Saeed & Flörke, 2006) as well as the intermolecular N–H···S hydrogen bonds (Table 2, Fig. 2), forming centrosymmetric dimers which are stacked along [001]. Two intermolecular C–H···S interactions with somewhat longer H···S distances are also present (see the hydrogen bonding table). Additionally, the typical (Saeed & Flörke, 2006) intramolecular N–H···O hydrogen bond is formed with the carbonyl function.

Experimental top

A solution of freshly distilled pivaloyl chloride (1.20 g, 10 mmol) in acetone (50 ml) was added dropwise to a suspension of potassium thiocyanate (0.97 g,10 mmol) in acetone (30 ml) and the reaction mixture was refluxed for 30 min. After cooling to room temperature, a solution of 3-methoxyaniline (10 mmol) in acetone (10 ml) was added and the resulting mixture refluxed for 2.0 h. The reaction mixture was poured into cold water and the resulting precipitate was isolated by filtration followed by recrystallization from ethanol to afford the title thiourea compound as colourless crystals (2.33 g, 83.0 mmol, 83%). m.p. 352 K.

Refinement top

Hydrogen atoms were located in difference syntheses, refined at idealized positions riding on the C (C–H = 0.95–0.99 Å) or N (N–H = 0.88 Å) atoms with isotropic displacement parameters Uiso(H) = 1.2U(Ceq / Neq) and 1.5(methyl-C). Methyl H atoms were refined on the basis of rigid groups allowed to rotate but not tip.

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.
