The title thiourea derivative, C14H18N4O5S, features two substantial twists between its component fragments: the dihedral angle between the SN2C (thiourea) and ONC2 (amide) residues is 48.89 (7)° and that between the benzene ring and the amide residue is 30.27 (7)°. In the crystal, molecules are linked by bifurcated N—H⋯(O,S) hydrogen bonds, generating [001] supramolecular chains.

A solution of 3,5-dinitrobenzoyl chloride (0.01 mol) in anhydrous acetone (75 ml) and 3% tetrabutylammonium bromide (TBAB) as a phase-transfer catalyst (PTC) in anhydrous acetone was added drop-wise to a suspension of dry potassium thiocyanate (0.01 mol) in acetone (50 ml) and the reaction mixture was refluxed for 50 min. After cooling to room temperature, a solution of dipropyl amine (0.01 mol) in anhydrous acetone (25 ml) was added drop-wise and the resulting mixture refluxed for 3 h. Hydrochloric acid (0.1 N, 300 ml) was added and the solution was filtered. The solid product was washed with water and purified by re-crystallization from ethyl acetate to yield light-yellow prisms of (I). Yield: 1.29 g (82%); M.pt. 407–408 K. IR (KBr, cm-1): 3173 ν(NH), 1690 ν(C═O), 1536 ν(benzene ring), 1180 ν(C═S). Anal. Calcd. for C14H18N4O5S: C, 47.45; H, 5.12; N, 15.81; S, 9.05%. Found: C, 47.53; H, 5.17; N, 15.75; S, 9.03%.
Carbon-bound H-atoms were placed in calculated positions [C—H 0.93–0.97 Å, Uiso(H) 1.2–1.5Ueq(C)] and were included in the
in the riding model approximation. The amino H-atoms were located in a difference Fourier map, and were refined with a distance restraint of N—H 0.88±0.01 Å; the Uiso values were refined. The maximum and minimum residual electron density peaks of 1.04 and 0.46 e Å-3, respectively, were located 1.05 Å and 0.33 Å from the C2 and H2a atoms, respectively.Data collection: CrysAlis PRO (Agilent, 2010); cell

The biological potential of thiourea derivatives (Venkatachalam et al., 2004; Saeed et al., 2011) motivates structural studies of these compounds (Gunasekaran et al. 2010; Saeed et al. 2010; Dzulkifli et al., 2011). Herein, the crystal and molecular structure of the title thiourea derivative, (I), is described.
The molecular structure of (I), Fig. 1, shows a significant twist around the central atoms as seen in the value of the dihedral angle formed between the least-squares planes through the S1,N1,N2,C7 (thiourea) and O1,N2,C8,C9 (amide) atoms of 48.89 (7) °. Further, the benzene ring is twisted out of the plane of the carbonyl residue as indicated by the O1—C8—C9—C10 torsion angle of 147.1 (2) °. With respect to the S1,N1,N2,C7 plane, the n-propyl groups lie to either side. Whereas the O2-nitro group is co-planar with the benzene ring to which it is bonded, the O2—N3—C11—C10 torsion angle = -4.2 (3) °, the O4-nitro group is slightly twisted out of the plane as seen in the value of the O4—N4—C13—C12 torsion angle of -9.3 (3) °.
The crystal packing is dominated by N—H···O,S hydrogen bonds as the N1—H H atoms is bifurcated, Table 1. These result in the formation of six-membered {···H···OCNCS} synthons and linear supramolecular chains along the c direction, Fig. 2.
