In the title Schiff base compound, C14H13N3O3, the furan and benzene rings are oriented at a dihedral angle of 10.24 (13)°. Intramolecular N-H
O hydrogen bonding is observed between the imino and nitro groups.
2-Nitrophenylhydrazine (1 mmol, 0.153 g) was dissolved in anhydrous ethanol (15 ml). The mixture was stirred for several min at 351 K, then the furylideneacetone (1 mmol, 0.136 g) in ethanol (8 ml) was added dropwise and the mixture was stirred at refluxing temperature for 2 h. The product was isolated and recrystallized from methanol, red single crystals of (I) were obtained after 3 d.
All H atoms were positioned geometrically and refined as riding with C—H = 0.93 (aromatic), 0.96 Å (methyl) and N—H = 0.86 Å, and refined in riding mode with Uiso(H) = 1.5Ueq(C) for methyl H atoms and Uiso(H) = 1.2Ueq(C,N) for the others.

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. |

4-Nitrophenylhydrazine has applications in organic synthesis, and some of its derivatives have been shown to be potentially DNA-damaging and mutagenic agents (Okabe et al., 1993). As part of our work, the title compound (I) is synthesized in our group, and its structure is reported here (Fig. 1).
The molecular structure is non-planar, there is a dihedral angle of 9.19 (9)° between the benzene ring and the N2/N1/C7/C6/C5 plane, while the N2/N1/C7/C6/C5 planar and the furyl ring is nearly planar, making a dihedral angle of 4.26 (11)°. The furan and benzene rings are oriented at a dihedral angle of 10.24 (13)°. Intramolecular N—H···O hydrogen bonding is present between imino and nitro groups (Table 1).
