The title compound, C14H10BrN3O3S, crystallizes as two concomitant polymorphs that differ in colour (one yellow and one colourless). Only the structure of the colourless form could be determined. The mol­ecule exists in the thio­amide form with an intra­molecular N—H⋯O=C hydrogen bond across the thio­urea system. Mol­ecules are linked into layers parallel to (120) by Br⋯Onitro contacts [3.103 (1) Å], classical hydrogen bonds from the other NH function to the S atom and Nnitro⋯O=C contacts. The layers are linked by weak C—H⋯Onitro hydrogen bonds to produce the observed three-dimensional network.

Industrial production and the use of elements such as Fe, Co, Cu, Ni, Zn, Cd and Pb can cause environmental pollution. However, some of these metals are present in trace amounts as essential elements for biological systems and also play an important role in bioinorganic chemistry. In order to understand the role of these metal ions in biological systems, structural studies of biological compounds and their metal complexes are extremely important. Compounds containing carbonyl and thiocarbonyl groups occupy an important position among organic reagents as potential donor ligands for transition metal ions (Ugur et al., 2006).

Thioureas are also known to exhibit a wide range of biological effects including antiviral, antibacterial, anticancer (Manjula et al., 2009), antifungal, antitubercular, antithyroidal, herbicidal and insecticidal activities (Huebner et al., 1953) and are used as agrochemicals (Saeed et al., 2008a<i/>). An example is furnished by 1-benzoyl-3-(4,5-disubstituted-pyrimidine-2-yl)- thioureas that have excellent herbicidal activity (Zheng et al., 2004). Thioureas are also well known chelating agents for transition metals (Saeed et al., 2008b<i/>). The complexes of thiourea derivatives also show varied biological activities (Glasser et al., 1964). Thioureas and substituted thioureas are also known as epoxy resin curing agents (Saeed et al., 2008b<i/>). We became interested in the synthesis of N-aroyl, N'-arylthioureas as intermediates towards some new heterocyclic compounds and for the systematic study of their bioactive complexes and their function as epoxy resin curing agents, and have recently published three structures from this compound class (Saeed et al., 2008a,b,c).

The molecule of the title compound is shown in Fig. 1. It crystallizes in the thioamide form with an intramolecular hydrogen bond N1—H01···O1. Bond lengths and angles may be regarded as normal. The central moiety N1—C7( S)—N2—C8(O1) is essentially planar (mean deviation 0.09 Å) and subtends interplanar angles of 38.42 (4)° and 56.27 (4)° with the aromatic rings at C1 and C9, respectively. This is also reflected by the corresponding torsion angles C7—N1—C1—C6 43.7 (2)° and N2—C8—C9—C14 - 50.8 (2)°.

The molecular packing is determined by a variety of intermolecular contacts. The molecules are linked to chains parallel to [211] by the halogen bond Br···O2 3.103 (1) Å, with an angle C4—Br···O2 of 176.07 (5)° (operator: x - 2, y + 1, z + 1). The chains are crosslinked by the classical H bond N2—H02···S (Table 1) and the contact N3···O1 2.957 (1) Å, with an angle C12—N3···O1 of 88.60 (7)° (operator: -x + 1, -y + 1, -z), to form layers parallel to (120). The layers are connected by the weak H bond C5—H5···O3 to give the observed three dimensionial structure (Table 1). Further borderline H···X interactions are also listed in Table 1 for the sake of completeness but are probably of minimal structural relevance.

Experimental top

A solution of 4-nitrobenzoyl chloride (0.1 mol) in dry acetone (80 ml) was added dropwise to a suspension of ammonium thiocyanate (0.1 mol) in acetone (50 ml) and the reaction mixture was refluxed for 30 minutes. After cooling to room temperature, a solution of 4-bromoaniline (0.1 mol) in acetone (25 ml) was added and the resulting mixture refluxed for 1.5 h. The reaction mixture was poured into five times its volume of cold water, upon which the thiourea precipitated. The product was recrystallized from ethyl acetate as intensely yellow crystals. However, these crystals, despite near-perfect optical appearance under the microscope, proved to be unusable for X-ray analysis because their diffraction patterns were very weak and diffuse. A few large colourless prisms were therefore selected from the same sample and proved to be of diffraction quality. Clearly the title compound is polymorphic, and one may speculate that the different colours may arise from different H bonding patterns.

Refinement top

The NH hydrogen atoms were refined freely, but with an N—H distance restraint of 0.82 Å and an associated notional e.s.d. of 0.02 Å (command DFIX). Other H atoms were placed in calculated positions and refined using a riding model with C—H 0.95 Å; the hydrogen U values were fixed at 1.2 × U(eq) of the parent atom. The largest features of residual electron density (ca 0.8 e Å-3) lie within 1 Å of the Br atom.

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.
