The title compound, C14H12N4O4, was prepared by the reaction of 2-nitrophenyl isocyanate with benzoylhydrazine. The dihedral angle between the rings is 71.49 (6)) Å. The molecular conformation is stabilized by an intramolecular N-H
O hydrogen bond, generating an S(6) ring. The crystal packing shows N-H
O hydrogen bonds.
2-nitrophenyl isocyanate(0.164 g, 1 mmol) and benzoyl hydrazine (0.136 g, 1 mmol) were milled and mixed thoroughly in an agate mortar. Then the mixture was put into a beaker and irradiated by microwave for 1 min. After the reaction was completed, the resulting mixture was dissolved in 95% ethanol and filtrated. The products separated and were collected by filtration. The title compound was recrystallized from ethanol and single crystals were obtained by slow evaporation.
In the absence of anomalous scatterers, the absolute structure could not be determined and, therefore, Friedel pairs were merged. All H atoms bonded to C atoms were placed in calculated positions, with C—H = 0.95 Å, and included in the refinement using a riding model, with Uiso(H) = 1.2Ueq(C). H atoms bonded to N were freely refined.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

Urea derivates are very interesting reagents due to their useful properties and important medical and biological applications. For example, aryl urea derivates have been found to inhibit cell division as weedicides, and homologous aryl urea derivates have also been researched as antibacterial activity. Thidiazuron, a substituted heterocyclic urea compound, mimicked the effect of benzyladenine(BA) in the Ca2+ + cytokinin system and the IAA + cytokinin systems systems. (Yip et al., 1986). Recently, better activity of sectiona benzoyl urea derivates were reported. (Liu et al., 2005). In order to discover further biologically active urea compounds, the title compound was synthesized and its crystal structure was determined (Fig. 1). The molecular conformation is stabilized by an intramolecular N—H···O hydrogen bond. The crystal packing shows N—H···O hydrogen-bonds. (Fig. 2).
