Ethyl 2-[3-(3,5-Dinitrobenzoyl)thioureido]benzoate

S. Saeed, N. Rashid, M. H. Bhatti and W.-T. Wong

Abstract top

In the title compound, C17H14N4O7S, the dihedral angle between the two benzene rings is 9.04 (15)°. The centroid-centroid distance of 3.9825 (19) Å between nearly parallel benzene rings of adjacent molecules suggests the existence of [pi]-[pi] stacking. Intermolecular and intra-molecular N-H...O hydrogen bonding is present in the structure. The ethoxy group is disordered over two sets of sites with an occupancy ratio of 0.580 (15):0.420 (15). The crystal studied was an inversion twin.

Comment top

The background to this study has been set in our previous work on the structural chemistry of N,N'-disubstituted thiourea (Saeed et al., 2010). Herein, as a continuation of these studies, the structure of the title compound, (I), C17H14N4O7S, is described.

The compound is slightly twisted. The nitro groups are 3.9 (5)° and 17 (1)° from the phenyl ring plane of C10—C15. The thiourea plane is making a dihedral angle of 5.3 (2)° with the amido group and makes a dihedral angle of 31.35 (17)° with the phenyl ring plane of C2—C7.

There are inter-molecular N—H···O H-bond interactions which link the molecules to form 1-D chain in the crystal lattice. There are also weak π···π between neighbouring rings in the crystal lattice.

Experimental top

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 dropwise 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 ethyl-orthoamino benzoate (0.01 mol) in anhydrous acetone (25 ml) was added dropwise 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.

Refinement top

N-bound H-atoms were located in a difference Fourier map and refined isotropically. Other H atoms were placed at geometrical positions with C—H = 0.93–0.97 Å and refined using riding model with Uiso(H) =1.2Ueq(C). The ethoxy group is disordered over two sites, the occupancy ratio was refined to 0.580 (15):0.420 (15). Distance and displacement restraints were used for the disordered components.

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.
