1,1′-Diphenyl-3,3′-(p-phenylenedicarbonyl)dithiourea

W. W. Hung, I. N. Hassan, B. M. Yamin and M. B. Kassim

The molecule of the title compound, C₂₂H₁₈N₄O₂S₂, lies across a crystallographic inversion centre. The central benzene ring forms dihedral angles of 29.39 (9) and 79.11 (12)°, respectively, with the thiourea unit and the terminal phenyl ring. Intramolecular N—H

O hydrogen bonds generate two S(6) ring motifs. In the crystal, molecules are linked into chains along [1 $\overline{1}$ 0] by intermolecular N—H

S hydrogen bonds.

Comment top

The asymmetric unit of the title compound contains one-half of the molecule the other half being generated by the crystallographic inversion centre (Fig. 1). The thiourea fragment (S1/O1/N1/N2/C6/C7/C8) is planar, with atom C8 has the maximum deviation of 0.038 (2)Å from the mean plane. The dihedral angle between the central bridging benzene ring and the thiourea unit is 29.39 (9)° and that between the two benzene rings is 79.11 (12)°. The carbonyl and N-H groups are involved in intramolecular N—H···O hydrogen bonding resulting in the formation of two six-membered rings viz. C7/N2/C8/O1/H1A/N1 and C7A/N2A/C8A/O1A/H1AA/N1A. The C═O bond length of 1.220 (3) Å is longer than the average C═O bond length (1.200 Å). These features are similar to those observed in the structure of N-benzoyl-N'-(3-pyridyl)thiourea (Dong et al., 2006). Bond lengths are in normal ranges (Allen et al., 1987).

In the crystal structure, intermolecular N—H···S hydrogen bonds (Table 1) link the molecules into a chain along the [110] (Fig 2).

Experimental top

The title compound was synthesized according to a previously reported method (Hassan et al., 2008) with some modification. Terephthaloyl chloride (1.015 g, 0.5 mmol) was added to ammonium thiocyanate (0.770 g, 1 mmol) in tetrahydrofuran and the contents were stirred for 10 min. The precipitated ammonium chloride was removed by filtration and then aniline (1.0 ml, 1 mmol) in methanol was added dropwise. The mixture was refluxed for 5 h and the black coloured solution was dried using a evaporator before it was washed with cool methanol. Yellow crystals of the title compound were obtained by recrystallization from DMF.

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.
