N-(3-Methyl­phen­yl)-N′-(4-nitro­benzo­yl)thio­urea

Abstract

Two mol­ecules of the title compound, C15H13N3O3S, are linked by an inter­molecular N—H(...)S hydrogen bond. There is also an intra­molecular N—H(...)O hydrogen bond, forming a six-membered ring. The steric restriction of the m-methyl and p-nitro groups, as well as the intra­molecular hydrogen bond, are the main factors influencing the mol­ecular conformation.

Comment

Thiourea and its derivatives are good ligands for forming coordination compounds with transition metal ions, especially Cu(I). Our previous research showed that coordination compounds of carbonylthiourea derivatives with Cu(I) often adopt a trigonal planar conformation (Xian et al., 2004). In addition, it was found that the reaction of carbonylthiourea derivatives with Cu(I) can also form a metal cluster compound with a complex structure (Su et al., 2005). Apparently, the coordinating ability of carbonylthiorea derivatives is related to their conformation and hydrogen bonds. Herein the structure of N-p-nitrobenzoyl-N'-(m-methylphenyl)thiourea and its FT—IR, 1H NMR was reported.

As shown in Fig. 1, the title compound adopts a trans-conformation similar to the other structures of thiourea derivatives (Su et al., 2006; Su, 2007), i.e. the conformation in which the thiocarbonyl and carbonyl groups are distributed on opposite sides of the main backbone due to steric restriction. On the other hand, steric restriction and hydrogen bond interactions also result in dimer formation through the "head-tail" junction conformation of the title compound (Fig. 2). The thiocarbonyl group forms an intermolecular hydrogen bond with N—H (-x, -y, -z), and the carbonyl group forms intramolecular hydrogen bond with N—H (x, y, z). Apparently, the carbonyl oxygen atom is "locked" in the hydrogen-bonded six-membered ring structure and thus not readily available for coordination with transition metal ions. There are mainly two molecular planes in the structure, two benzene rings almost are in the same plane with the mean deviation 0.078 (4) Å, another plane is the hydrogen-bonding six-membered ring with the mean deviation 0.055 (4) Å. The angle between two benzene planes is 41.39(0.09)°. The above conformation is similar to that observed in previously reported thiourea structures (Su, 2005; Yusof et al., 2007).

Experimental

All chemicals used for the preparation of the title compound were of reagent grade quality. The infrared spectrum was recorded in the range of 4000–400 cm-1 on a Nicolet NEXUS 670 F T—IR spectrometer, using KBr pellets. 1H NMR spectrum was obtained on an INOVA-400 MHz superconducting spectrometer, CDCl3 was used as the solvent and TMS as internal standard, and the chemical shifts are expressed as delta. Elemental analyses were carried out on a PE-2400 elemental analysis instrument. Melting point determination was performed in YRT-3 melting point instrument (Tianjin) and was uncorrected. The yellow single-crystal was obtained after one week by slow evaporation of the acetone solution of the title compound. N-p-nitrobenzoyl-N'-(m-methylphenyl)thiourea. Color: yellow. Melting Point: 151–153 (°C). Elemental analysis (%) found (calcd.): C, 56.3(61.5); H, 4.11(4.7); N, 10.3(13.2); S, 10.2(10.0). IR (KBr, cm-1): 3244 (N—H), 1675 (C=O), 1521(C=C), 1336, 1264(C=S), 1151. 1H NMR(delta, p.p.m.): 2.40 (s, 3H, CH3); 6.91–9.07 (m, 8H, C6H4, C6H4); 12.30 (s, 1H, NH).

Refinement

The amino hydrogen atoms were found from Fourier difference maps and fixed with N—H bond lengths of 0.86 Å. The H atoms of the aromatic group were geometrically idealized. The methyl H atoms were idealized to tetrahedral geometry and allowed to freely rotate about the C-C vector. All the H atoms were refined isotropically with isotropic vibration parameters related to the atoms to which they are bonded.

Special details

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.
