The molecule of the title compound, C22H18N4O2S2, lies across a crystallographic inversion centre. The molecule adopts a syn–anti configuration with respect to the positions of the carbonyl groups and terminal phenyl rings relative to the thione S atom across the C—N bond. There are two intramolecular N—H⋯O and C—H⋯S hydrogen bonds within each molecule, resulting in the formation of four six-membered S(6) rings. The central and terminal rings make a dihedral angle of 13.55 (15)°. In the crystal, molecules are linked by intermolecular C—H⋯S hydrogen bonds, forming R22(14) rings and resulting in zigzag chains.

The title compound was synthesized according to previously reported method with some modification (Thiam et al. 2008). Benzoyl chloride (10 mmol) was added to ammonium thiocyanate solution (10 mmol) and the mixture was left to react to completion. A yellowish product was filtered and added to a 1,4-diaminobenzene (5 mmol) in acetone and left at a refluxing temperature for 5 h. Yellowish precipitate was formed and a slow evaporation of the DMF solution of the product gave a crystal suitable for X-ray diffraction (Yield:75%).
All H atoms attached to C and N were calculated and treated as riding on their parent atoms with C-H= 0.93Å and N-H= 0.86Å with Uiso=1.2Ueq (C, N).
The title compound (Fig. 1) is a benzoyl thiourea derivatives and analogous to 1,2-bis(N'-benzoylthioureido)benzene, (Thiam et al., 2008), except that the other thiourea moiety is located in para position of the centre benzene ring. It is also an isomer of 1,1'-Diphenyl-3,3'-(p-phenylenedicarbonyl)dithiourea which was reported perviously (Hung et al., 2010). The bond lengths and angles are in normal ranges (Allen et al., 1987). The C=O bond length of 1.227 (3)Å is longer than the average C=O bond length (1.200 Å) and comparable to that observed in N-benzoyl-N'-phenylthiourea (Yamin et al., 2003). The C—N bond lengths are in the range of 1.330 (3) Å-1.415 (3)Å which are shorter than the normal single C—N bond length (1.469 Å) indicating double bond character (Arslan et al. 2004) owing to the
at the carbonyl-thiourea moiety. The thiourea fragment (S1/O1/N1/C6/C7/C8) is planar with a maximum deviation from its mean plane of 0.044 (3)Å for C8 atom. The central and terminal phenyl rings are essentially planar. The two rings make dihedral angles of 2.19 (13)° and 12.24 (15)°, respectively, with the thiourea fragment and the dihedral angle between those two rings is 13.55 (15)°.As in most of the benzoyl thiourea derivatives, N–H···O intramolecular hydrogen bonding lead to the formation of two six membered S(6) rings [Etter et al., 1990; Bernstein et al., 1995) namely, C7/N1/C8/N2/H2/O1 and C7i/N1i/C8i/N2i/H2Ai/O1i (Fig. 1, Table 1). There are also weak C-H···S intramolecular hydrogen bonds involving resulting in another two S(6) rings (C8/N2/C9/C11/H11/S1 and C8i/N2i/C9i/C11i/H11i/S1i). In the
molecules are linked by intermolecular C–H···S hydrogen bonds (Table 1) building R22(14) rings (Etter et al., 1990; Bernstein et al., 1995) (Fig. 2). Owing to the fact that the molecule is organised around an inversion center, these rings extend on each side of the molecule to form azigzag chain.For related compounds and structural parameters, see: Hung et al. (2010), Thiam et al. (2008); Arslan et al. (2004); Yamin et al., (2003). For bond-length data, see: Allen et al. (197). For hydrogen-bond motifs, see: Etter et al. (1990); Bernstein et al. (1995).

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. |

The title compound (Fig. 1) is a benzoyl thiourea derivatives and analogous to 1,2-bis(N'-benzoylthioureido)benzene, (Thiam et al., 2008), except that the other thiourea moiety is located in para position of the centre benzene ring. It is also an isomer of 1,1'-Diphenyl-3,3'-(p-phenylenedicarbonyl)dithiourea which was reported perviously (Hung et al., 2010). The bond lengths and angles are in normal ranges (Allen et al., 1987). The C=O bond length of 1.227 (3)Å is longer than the average C=O bond length (1.200 Å) and comparable to that observed in N-benzoyl-N'-phenylthiourea (Yamin et al., 2003). The C—N bond lengths are in the range of 1.330 (3) Å-1.415 (3)Å which are shorter than the normal single C—N bond length (1.469 Å) indicating double bond character (Arslan et al. 2004) owing to the resonance effect at the carbonyl-thiourea moiety. The thiourea fragment (S1/O1/N1/C6/C7/C8) is planar with a maximum deviation from its mean plane of 0.044 (3)Å for C8 atom. The central and terminal phenyl rings are essentially planar. The two rings make dihedral angles of 2.19 (13)° and 12.24 (15)°, respectively, with the thiourea fragment and the dihedral angle between those two rings is 13.55 (15)°.
As in most of the benzoyl thiourea derivatives, N–H···O intramolecular hydrogen bonding lead to the formation of two six membered S(6) rings [Etter et al., 1990; Bernstein et al., 1995) namely, C7/N1/C8/N2/H2/O1 and C7i/N1i/C8i/N2i/H2Ai/O1i (Fig. 1, Table 1). There are also weak C-H···S intramolecular hydrogen bonds involving resulting in another two S(6) rings (C8/N2/C9/C11/H11/S1 and C8i/N2i/C9i/C11i/H11i/S1i). In the crystal structure, molecules are linked by intermolecular C–H···S hydrogen bonds (Table 1) building R22(14) rings (Etter et al., 1990; Bernstein et al., 1995) (Fig. 2). Owing to the fact that the molecule is organised around an inversion center, these rings extend on each side of the molecule to form azigzag chain.
