Supporting information
A mixture of the acetyl furan (11 g, 0.10 mol), and propionylhydrazine (8.8 g, 0.10 mol) was stirred in refluxing ethanol (30 ml) for 5 h to afford the title compound (17 g, 0.087 mol, yield 87%). Single crystals suitable for X-ray measurements were obtained by recrystallization from ethanol at room temperature.
H atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances = 0.93–0.98 Å, and with Uiso=1.2–1.5Ueq(C).

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. |

Schiff bases have received considerable attention in the literature, and are attractive from several points of view, such as the possibility of analytical application (Cimerman, et al., 1997). As part of our search for new schiff base compounds, we synthesized the title compound (I). The C7—N2 bond length [1.343 (2) Å] is longer than the typical value for a double bond, but less than for a single bond, due to conjugation effects within the molecule.
Bond lengths and angles in the phenyl ring are normal. The C5—N1 distance of 1.280 (2) Å is similar to the similar distance of 1.287 (2) Å reported in a corresponding compound (Tucker et al., 1975). Similarly, the C7—O2 distance of 1.226 (2) Å is shorter than the similar distance of 1.298 (2) Å reported by Sutherland et al., 1968.
